Lecce want a late consolation. Calderoni carries the ball forward but drags a poor shot well, well wide. That should be that.
88'
Now Gabriel saves again, albeit from a tamer shot as Higuain's attempt deflects through to the grateful goalkeeper.
85'
M. de Ligt has scored a goal for Juventus! Assist by Douglas Costa.
GOOAAALLLL!!! DE LIGT! It's 4-0, a scoreline which is arguably both deserved for Juve and harsh on Lecce. The 10 men are clearly tired as they are slow to get out to a short corner, allowing Costa to send a wicked centre bouncing through the box to De Ligt, who nods in from a couple of yards out.
Costa was not involved in the first goal but his arrival prompted the breakthrough and he has been brilliant ever since, providing a superb assist now.
83'
G. Higuaín has scored a goal for Juventus!
GOOAAALLLL!!! HIGUAIN! It's three! The substitute finishes smartly, lifting a shot over Gabriel, but this goal owes so much to Ronaldo for a wonderful assist, carrying the ball from halfway before cutting inside and backheeling through to his strike partner with the aid of a deflection. 3-0!
81'
Lecce occasionally see an opportunity to counter, continuing to pursue chances in attack. But Szczesny has enjoyed a really straightforward second half, simply sweeping up the odd long ball.
78'
M. Calderoni enters the game and replaces B. Vera.
The changes keep coming as Lecce take off Vera, with Calderoni introduced.
77'
G. Higuaín enters the game and replaces P. Dybala.
S. Muratore enters the game and replaces F. Bernardeschi.
The other Juve switch sees Bernardeschi off, giving Muratore his Serie A debut.
Dybala got the crucial goal and his work is done. He is replaced by Higuain in a double-change.
72'
A. Barák enters the game and replaces M. Mancosu.
Mancosu hands over the armband as his outing comes to an end. Barak is on for Lecce.
70'
To their credit, Lecce are still attempting to play out from the back. But they started this match with a deep, deep defensive line and their tired legs are not getting any further up the pitch.

Description
68'
A. Ramsey enters the game and replaces R. Bentancur.
Juve's second change brings further firepower, as Ramsey replaces Bentancur.
67'
Juve are not yet happy with their lot. They win a free-kick on the left, which Dybala takes. He so nearly picks out a lunging Bonucci, with the ball also bouncing beyond Ronaldo behind him.
64'
Babacar looks to make an immediate impact but sends a weak shot straight at Szczesny.
62'
Penalty goal scored by Cristiano Ronaldo for Juventus!
K. Babacar enters the game and replaces F. Falco.
GOOAAALLLL!!! Ronaldo makes no mistake! 2-0 Juve! Having won the penalty himself, the forward drills his second spot-kick of the week straight down the middle of the goal.
The game is surely gone for Lecce, but they make a change as Babacar replaces Falco.
60'
Szczesny is stood 40 yards from his own goal as Juve attempt to keep Lecce penned in. Ronaldo might well have an opportunity to score but for a wonderful lunging clearance from Rossettini deep inside the area.
58'
Easy stuff for Gabriel. Matuidi chooses not to look for a team-mate as he instead shoots from 25 yards, picking out the goalkeeper's gloves.
57'
A dash up the right brings Lecce brief hope of pushing Juve back, yet no foul is given following a clash and the champions can instead attack once more. Ronaldo is now stationed inside the Lecce box.
55'
This could be a long second half for 10-man Lecce now. Juve want another to put this game to bed.
53'
P. Dybala has scored a goal for Juventus! Assist by Cristiano Ronaldo.
GOOAAALLLL!!! DYBALA! There's the opener and it's a beauty! 1-0 Juve! Dybala picks his spot from the edge of the area, lifting a lovely curling left-footed effort past Gabriel into the top-right corner. Juve needed a moment of magic and they have it through their number 10.
Ronaldo, who has moved into the centre since Costa's arrival, collects the assist, although he does little more than prod a pass into Dybala's path.
52'
Douglas Costa enters the game and replaces A. Rabiot.
Sarri makes his change, bringing Costa on for Rabiot in an attacking move.
Costa has a swift impact! Darting down the right, he gets to the byline and cuts a cross back that somehow evades everyone in the centre.
50'
The tone is set for this second half. Juve are camped in the Lecce half, but Mancosu and Falco are working hard to provide an out ball. Rabiot's foul on the former lets Lecce regroup.
47'
Juve's early efforts are thwarted as Matudui clashes with Rispoli, who wins a free-kick and requires treatment but can continue.
46'
L. Rossettini enters the game and replaces J. Petriccione.
Lecce make a change at the break, replacing midfielder Petriccione with centre-back Rossettini as they change shape following the red card.
KICK-OFF: We are back under way, with Juve in possession and in pursuit of a precious winner.
45' +3
HALF-TIME: Juventus 0-0 Lecce
45' +2
De Ligt cannot aim a header on target after Ronaldo's pressing on the left wins a corner from Rispoli. It is a difficult chance, leaning back 12 yards out.
45' +1
There will be a minimum of two minutes of added time.
Really good defensive work from Bentancur. A Lecce player beats De Ligt to a 50-50 on halfway, allowing the visitors to break. But Bentancur, on a booking, races back to fairly dispossess Falco.
45'
Juve are growing frustrated - somewhat understandably. Bentancur goes for goal from 20 yards but gets the shot all wrong.
40'
Gabriel comes for the set-piece and, along with the help of a defender, gets just enough on the ball to get it clear. Juve build again, though, and Dybala is next to cross and win a corner.
39'
Lecce just need to be careful in possession in their own third. They work out of trouble smartly, only for Tachtsidis to dally and lunge into a challenge that his opponent wins. Matuidi's cross is deflected, giving Juve a corner.
38'
R. Bentancur gets yellow.
Petriccione goes short from a corner and then draws a late challenge from Bentancur, who goes into the book and gives up a free-kick in a dangerous position on the left corner of the box.
This is a real waste. The free-kick is nudged square to Vera, yet he blasts a poor shot well off target.
36'
A well-timed tackle from Tachtsidis on the edge of the area frustrates Ronaldo, but Juve soon win a corner on the right. De Ligt is the man to go down this time, yet no foul is given in the centre.
33'
Ronaldo surprisingly chooses not to shoot from the free-kick following the red card, and Juve cannot work an opening. They should be in complete control now, though.
31'
F. Lucioni goes off after a red card!
RED!! Oh dear, oh dear. Lecce have played out from the back smartly, but a poor Lucioni touch proves so costly. He is 40 yards from goal but allows Bentancur to steal in and then go over a hanging leg. The defender is the last man and, despite his protests, is sent off.
30'
But back come Lecce. A teasing ball from the right causes the Juve defence some problems, with a hurried clearance only allowing the away team to build again.
28'
Not this time! Ronaldo moves down the left and crosses, his ball passing through to Bernardeschi on the far side. The right-sided winger lifts a delivery back across for Ronaldo, who attempts a spectacular overhead-kick. The forward does not catch this one sweet, though, and the ball skews wide.
27'
Lecce counter at speed, but Rispoli ignores his team-mates to aim a tame shot straight at Szczesny. The visitors would do well to make the most of their opportunities.
26'
Bernardeschi is flagged once more on the right wing. This is poor positional play rather than a mistimed run. He is finding space behind Vera but has not been able to exploit it yet.
25'
Juve captain Bonucci is eager to get his team going. He is forward in the left wing position to take a throw-in as the hosts aim to play with greater urgency.
23'
Bernardeschi is at least offering Juve an outlet. As in the opening moments, he runs in behind on the right, only to be flagged offside.
22'
Rispoli lofts a cross into the Juve area, with Mancosu unmarked for a moment as he leaps for the ball. Two defenders step in to clear, conceding a corner. It comes to little this time, though.
18'
Lecce go short with the kick before eventually crossing from a similar position, with Cuadrado up to head clear. Juve can counter three on one, but Ronaldo's pass is poor and a team-mate can only rescue a corner.
17'
Rispoli gets to the corner flag and wins a set-piece as his cross deflects behind off Matuidi. Maurizio Sarri looks a little concerned.
16'
Simple stop for Szczesny, but Lecce move the ball nicely again in response to Juve's probing. A gorgeous switch onto the toe of Rispoli gets Lecce up the pitch, before Pertriccione looks left. Mancosu works space for a low shot, but the goalkeeper gathers.
14'
Juve are just starting to take control of the match, but they are being frustrated in their attempts to break Lecce down. Cuadrado swings over a cross that goes straight out of play.
13'
Ronaldo wins a free-kick from Petriccione, which Dybala sends into a dangerous area. A defender beats Ronaldo to the ball, though, as the Juve star protests on the ground.
9'
Juve move down the right through Bentancur, but a Lecce defender goes down in the centre as he tussles with Rabiot under a high cross. A free-kick is given against Juve.
8'
Lovely from Lecce once more. Tachtsidis teases a smart pass into the Juve area, but Falco cannot quite work an angle for a shot. The better play is coming from the strugglers.
6'
Juve appeal in vain as Vera goes up for a header following a long ball and seemingly misses it entirely. The home players think he does get a touch, meaning a corner, but the officials disagree.
5'
Falco is just a step offside as Lecce look to get in behind the Juve defence on this occasion. This is a bright start from the visitors.
3'
Bernardeschi almost gets in, but he strays just offside! The winger marginally beats Gabriel in a race with the goalkeeper for the ball on Juve's right, yet the ball bounces behind and the flag is up.
2'
Unsurprisingly, Juve have quickly taken control of the possession, pinging early passes around the midfield.

KICK-OFF: Lecce get us under way!
Hello and welcome to our live text commentary of today's Serie A clash between Juventus and Lecce!
Defending champions and league leaders Juve are looking to stretch their advantage at the summit to seven points with victory. Title rivals Lazio threw away a two-goal lead to lose to Atalanta in midweek after the Bianconeri had beaten Bologna.
Lecce need the points, too, though, as they sit 18th, level on points with 17th-placed Genoa. Their form either side of the pause in the season has been slightly bizarre, winning three in a row - including a victory at Napoli - before losing their next three, conceding 15 in the process.
Let's get the team news from Turin...
Subs: Gianluigi Buffon, Carlo Pinsoglio, Aaron Ramsey, Douglas Costa, Gonzalo Higuain, Daniele Rugani, Marco Olivieri, Simone Muratore, Wesley.
Juventus (4-3-3): Wojciech Szczesny; Juan Cuadrado, Matthijs de Ligt, Leonardo Bonucci, Blaise Matuidi; Rodrigo Bentancur, Miralem Pjanic, Adrien Rabiot; Federico Bernardeschi, Paulo Dybala, Cristiano Ronaldo.
Even with Juve clear at the top of Serie A, coach Sarri remains under pressure. Performances like this are unlikely to ease his situation. For all that Lecce have played well and Juve still should have scored twice, the Bianconeri have been really poor.
The Bianconeri will look for Lazio's result against Fiorentina tomorrow with great interest before preparing to face Genoa on Tuesday. Lecce would welcome a Juve win there as their relegation battle continues with a crucial clash at home to Sampdoria.
That's all from this one, where Juve have secured another three points towards their title tilt. Thanks for joining us and, until next time, goodbye!
