Excellent goalkeeping by Keylor Navas keeps Real in this game. Lionel Messi runs from the centre circle onto a long ball forward, Navas holds his ground and dives to keep out the Argentine's effort as he enters the box.

A slightly unexpected stat is that Lucas Vazquez has played more Real Madrid games than any other player under Zinedine Zidane. You probably wouldn't guess second place either - Isco.

Real Madrid bring on Lucas Vazquez, usually a winger, at right-back as he replaces Nacho. Vazquez played there against Bayern Munich.

Real sub Marco Asensio airkicks an attempted volley from very near where Luis Suarez struck the opener.

mediocre in every way: Bale looks finished at the top level, if he wants to stay at Madrid or start the final he needs to step up in this half hour (probably already too late tho)

abatunde sakiru: If Real Madrid loses today Zidane should take responsibility from shambolic substitution. Why on the heart will a first-class manager make such decision? Ridiculous!!!

Marco Asensio crosses and Karim Benzema slips as the ball goes behind him. Things just aren't clicking for Real here. They were playing better when Barca had 11 men. Bring Sergi Roberto back on.

The ball breaks for Gareth Bale in the box but Samuel Umtiti just eases him off the ball. An in-form confident Bale probably beats Umtiti there.

I haven't seen a better 10-man performance since Oxford beat Swindon 2-0 after James Constable's red card in 2012...

It's not going to be eight for now as Lionel Messi just blasts the free-kick into the wall.

Lionel Messi buys a free-kick in a good position as Casemiro and Nacho combine to bring him down.

He's already scored seven free-kicks this season...

Real Madrid look shell-shocked, they've barely done anything since taking off Cristiano Ronaldo at half-time. Captain Sergio Ramos is walking the disciplinary tightrope at the moment.

Paulinho is inches away from doubling Barcelona's lead here. He tries to turn home a Nelson Semedo cross but instead crashes his studs into Keylor Navas' chest.

He hasn't actually touched the ball yet.

A huge standing ovation as Andres Iniesta's El Clasico career comes to an end. He's only lasted 57 minutes today - presumably for tactical reasons - and he's replaced by Paulinho.

He gives Lionel Messi the armband.

Never change Gerard Pique, never change. For some reason he's up in the striking position for Barcelona in open play. His side are ahead and down to 10 men. Sure, why wouldn't he?

No Cristiano Ronaldo to get Real Madrid back into this game now.

Luis Suarez has the ball in the net again for Barca but the referee's whistle had already gone for offside.

Marco Asensio goes on a good run, breaks into the box but then his shot is right at Marc-Andre ter Stegen.

Reports in Spain say Cristiano Ronaldo has a "slight ankle sprain" - no point taking any risks with three weeks to go until the Champions League final.

Real Madrid are having most of the ball so far in this second half. Good interchange from Karim Benzema and Marcelo, whose cross is cut out.

Garett Switzer: classic referee mistake; bale unpunished because he was issuing too many yellows in short span, then overreacts with harsh red card to try to regain control. inconsistent.

Helles Mammut: Only the second Barca player to be sent off in a Clasico in 10 years - in both games the result was already meaningless. But don't let the facts bother you, the Barca players and press will cry anyways. Now wait for their playacting in to get a Real player sent off
