Another Barcelona defender is now down injured, this time Jordi Alba. Gareth Bale catches the left-back with a follow-through.
That is almost unbelievable.

"That is a penalty. That is ridiculous. He wraps both arms around him and pulls him to the floor."
Real Madrid want a penalty as Dani Alves has his arms around Cristiano Ronaldo in the box - and they're a bit unlucky not to get it.
Poor lamb, Dani, probably just wanted a hug.
Barcelona defender Javier Mascherano is down injured after James Rodriguez caught him with a follow-through boot.
The former West Ham reserve midfielder is fit to come back on though, to Barca's relief.
Andres Iniesta plays a fantastic ball over the top to Sergi Roberto, but Marcelo holds him off and stops him getting a shot in. The Spaniard pulls it back to Ivan Rakitic, whose shot is blazed over.
Worrying times for Rafa Benitez, who has not lost a home match in the league at Real Madrid yet.

Quote MessageReal Madrid let them walk up to 40 or 50 yards away from goal. A great ball and finish but you can't let this team play once they get to the halfway line.
Luis Suarez
The 18th Barcelona La Liga goal in a row scored by either Neymar or Suarez. Sergi Roberto, starting ahead of Lionel Messi, plays a brilliant through ball to Luis Suarez, who hits it first time from 16 yards out.
Cristiano Ronaldo knocks the ball past Javier Mascherano and gets it on the other side but his shot, from a wide angle, is parried away by Claudio Bravo in Barcelona's goal.
Ambitious.
It's an open game and at the other end Karim Benzema is denied by a tackle moments after Neymar's shot.
We often get an early goal in El Clasico. Are we going to see one here?
First chance of the game as Jordi Alba plays the ball into Luis Suarez, who lays the ball off for Neymar but the Brazilian fires over.
Chris Waddle says "you'd think the form Neymar is in, he'd at least hit the target" on BBC Radio 5 live.
Barcelona defender Gerard Pique is getting a lot of boos from the home crowd, presumably because of his pro-Catalan independence stance. More understandable today than when it happens while he's playing for Spain.
Neymar gets the ball in an attacking position for the first time but the Brazilian, in the form of his life, gets his cross all wrong and it goes out for a goal-kick.
Corner comes to nothing but Real are building a decent spell of possession. And as I write that Karim Benzema sees the ball fly past him and out for a throw-in.
Cristiano Ronaldo tries a trick and the ball comes off Barcelona defender Gerard Pique. The first corner of the day.
Sergio Ramos clatters Luis Suarez in the opening minute. Referee talks to him, I suspect that would be a yellow card if it wasn't in the first few seconds.
