Finally the second half is under way.

Well Real Madrid are taking their time to come out the tunnel. Atleti players were stood waiting in position whilst Real players strolled on.

This is Koke's 748th appearance for Atletico Madrid. Only seven players have ever played more for one European team.

The 34-year-old could overtake three more players this season including Francesco Totti. He recently passed Bobby Charlton.

Atletico are making a half-time sub as Koke replaces the booked Marc Pubill.

Atletico's players are out first.

Almost time for the second half. Surely it's going to be better.

There were 13 fouls in that first half (10 by Atletico) and zero 'big chances' as defined by Opta.

Two of Atletico's backline plus their manager were booked.

There's a huge number of whistles ringing out across the stadium as the players head down the tunnel. Tensions feel very, very high.

In terms of bite and edge, everything you want from a derby.

Just not much actual football action.

It was a fair shoulder barge by Marc Pubill. To be fair to Kylian Mbappe he didn't appeal for a penalty.

Kylian Mbappe goes down in the box. No penalty.

Real make a mess of a good attack and then the offside flag goes up anyway.

Three minutes added on.

Alex Baena cuts the ball back to Jonathan David, who doesn't do anything with it. Atletico haven't had a shot on target yet.

Seven-goal Kylian Mbappe, who had a shot blocked a couple of minutes ago, has attempted 41 shots this season, more than any other La Liga player.

Raphinha has only needed 25 shots to score 12 goals.

The latest flashpoint sees Giuliano Simeone wrestle Kylian Mbappe to the ground and then the Real man catching him on the back of the head with his knee when getting back up. Accidental though - no cards.

It feels really hostile inside the Metropolitano at the moment. It feels like the game is struggling to find any sort of flow because of how many times the ref is having to stop play.

The first shot on target for either team as Real's Arda Guler has a go from outside the box with Jan Oblak palming it away.

So the ref booked Jude Bellingham but not Cristian Romero initially.

But after going to the screen he basically reversed both decisions. No red card for Romero though.

Cuti Romero ends up with a yellow card.

Tensions are so high here. Players are going to have to keep their discipline and not get caught up in the occasion here.
