Thanks for joining us today for a classic Clasico and the night Juventus showed they are title contenders again.
- Reaction to Real Madrid 0-4 Barcelona
- Suarez scores twice, second is Messi assist
- Messi comes on to return from injury
- Barca go six points clear
So Juventus move into sixth above AC Milan and close the gap on the leaders to six points. After a shocking start to the season, Juve are back in the title race.
That was the last chance of the game - Juventus win.
Alessio Cerci almost levels for AC Milan in the last minute from distance but Gianluigi Buffon tips his piledriver away.
Free-kick to Juventus, who look like they're taking the ball to the corner. But Alex Sandro has other ideas and squares the ball to Mario Mandzukic, who blazes over a woeful effort from inside the box.
Three minutes added on.
Milan don't really look like levelling here - Juventus on the attack as we approach injury time.
Actually maybe M'Baye Niang wasn't OK, he's just been replaced by Keisuke Honda.
Five minutes for one of AC Milan's talented attacking players to level this one up.
Juventus defender Stephan Lichtsteiner tries to volley home Alex Sandro's cross at the far post but he's tackled by M'Baye Niang's desperate last-ditch saving tackle.
Both players go down injured but they recover.
Neymar has scored in his last four competitive games for Barcelona in all competitions (six goals).
Juventus bring off their goalscorer Paulo Dybala for Alvaro Morata. Not a bad sub to have on the bench - Real Madrid could have done with him earlier.
Juventus defender Andrea Barzagli breaks and has a go but it's an awful effort from outside the box, miles wide.
The hosts have definitely been the better side, but Milan are still in this.
As things stand, Juventus are up to sixth - above AC Milan - and are only six points below the top three after turning around their abysmal start.
AC Milan bring off Juraj Kucka moments after I praise him, former Shakhtar Donetsk striker Luiz Adriano replaces him.
AC Milan's Juraj Kucka controls a cross on his chest but volleys over from 12 yards out. I've not seen too much of the Slovak this season, but he's looked decent today.
Luis Suarez has scored or assisted in his three games against Real Madrid (three goals, one assist).
Seconds later, Paulo Dybala tries to make it 2-0 but his shot from 25 yards is saved by AC Milan keeper Gianluigi Donnarumma.
The Juventus forward seems to have hurt himself.
Finally, something to write about. A great goal from Juventus' summer signing. Alex Sandro plays a one-two with Paul Pogba, who plays a brilliant return ball. Sandro crosses it in from the left and Paulo Dybala chests the ball before smashing his volley home.
Just realised 16-year-old Gianluigi Donnarumma is literally half my age.
Paul Pogba's ambitious effort from distance is tipped around the post by Gianluigi Donnarumma and the AC Milan child keeper punches the corner away to safety.
The ball rolls to AC Milan boss Sinisa Mihajlovic, who flicks the ball up in his polished black shoes and does a few keepy-ups. Was just missing one of his trademark 30-yard piledriver free-kicks.
There has been an average of 4.3 goals per game in the last nine league El Clasico encounters at Santiago Bernabeu.
Second half has been a bit more lively than the first and Juventus sub Alex Sandro cuts inside and fires an effort just high and wide.
Juventus defender Stephan Lichtsteiner is booked for fouling M'Baye Niang near the halfway line.
AC Milan's Giacomo Bonaventura wants a penalty as he is fouled by Leonardo Bonucci, who has only been on the pitch for seconds. But it's called back for a free out for a foul on Stefano Sturaro by M'Baye Niang, who headed the ball down to Bonaventura.
Lucky escape for Juventus.
Second half is now under way.
Juventus bring on defender Leonardo Bonucci for midfielder Hernanes at half-time.
Barcelona's 4-0 win was their second biggest win without conceding in a league away game against Real Madrid (5-0 in 1974).
Half-time at the Juventus Stadium. Not a classic.
The game between Panathinaikos and Olympiakos was called off before kick-off. A flare thrown onto the pitch exploded near an Olympiakos player. The champions refused to play and after an hour-long delay the game was called off.
That sparked a pitch invasion with fans fighting with police and ripping up seats.
Richard has attached a video of the chaos which you can see if you click on his tweet.
Paul Pogba fires an effort over from the edge of the box. Not sure he's hit the heights this season so far. A metaphor for Juventus' season perhaps.
Luis Suarez's first goal came after a build-up of 24 passes; the most for a La Liga goal in 2015-16 (24 passes).
Juventus bring off Patrice Evra, who has picked up a knock, and Alex Sandro comes on to replace him.
Barcelona's president is a happy man, unsurprisingly.
Claudio Marchisio has a go from 25 yards for Juventus but it's well saved by AC Milan keeper Gianluigi Donnarumma, who wears number 99.
