Two full-backs and a winger who sometimes dives on yellow cards for 70 minutes. What could go wrong?

Up to three yellow cards, 18 minutes in. Spain full-backs Jordi Alba and Dani Carvajal clash near the corner flag. Carvajal puts his hand in Alba's face - not sure what Alba did but they're both booked.

Barcelona's first touch in the box as Antoine Griezmann tries to control a pass but he's squeezed out by a Sergio Ramos-Raphael Varane combo.

I hope I won't have to bring this stat up again but...

Only once before has El Clasico produced consecutive competitive goalless draws - back in 1973.

They drew 0-0 at the Nou Camp just before Christmas.

Real Madrid's Karim Benzema has gone seven games without scoring against Barcelona, his worst run in El Clasico.

Second chance for Real Madrid but Toni Kroos pops over a shot from the edge of the box.

Ha ha ha Paul. Followed by "Gareth Bale was just about to come on but has to sit back down as Zinedine Zidane tells centre-back Eder Militao to get ready instead".

Real Madrid are putting in some good moves at the moment. Marcelo is having a good game going forward - although that's never been his problem.

Good defending by Gerard Pique to head Dani Carvajal's cross away from Isco after some nice Real work including a Fede Valverde backheel to Karim Benzema.

We have a yellow card. Now it's El Clasico. Real winger Vinicius Jr chases Nelson Semedo and nudges him over. Silly yellow really. Needless.

Lionel Messi's cross is past everyone and Marcelo keeps it in at the other side.

Real left-back Marcelo was one of the surprise names on today's team sheet, replacing Ferland Mendy.

Lewis: Bring back the cool Barcelona. The team that didn't have a sponsor on their shirt and a smiling Ronaldinho running rings round everyone.

First chance. Barca have-clear the corner to Karim Benzema, whose improvised volley from 20 yards lands on the roof of the net.

Real's first attack since that quick start - and they get a third corner - as Vinicius Jr's cross is blocked.

I wonder if Sergio Ramos has managed red cards in consecutive games before. I'm sure he's found a way.

John: Let’s hope there’s more spark to this one than the last time they met. Real still suffering since CR7 left, first time in living memory that they don’t have a top world class player in their ranks no disrespect to Kroos. Should be a couple of goals & a Ramos red card.

This is almost a good move by Barcelona - a nice passing exchange but Frenkie de Jong takes far too long to make a decision two or three times and gets squeezed off the ball.

Gerard Pique in being booed by Real Madrid fans shocker.

Real win a corner within 50 seconds. They play it short and Arturo Vidal blocks a cross for a second corner.
