Real Madrid need to keep their cool and not get desperate.

Yet another shot from outside of the box is dragged wide as Joselu has a go with better options ahead of him.

Carlo Ancelotti has played all his cards now, making his final change to bring Brahim Díaz on for goalscorer Toni Kroos.

Well that would have been a screamer!

With Atletico Madrid dropping further and further back, Real just can't break down their rivals.

So defender Antonio Rüdiger takes things into his own hands and smashes an effort narrowly wide from 40 yards out.

It was close, very close.

Jude Bellingham has a rare touch inside the opposition's penalty area but can't get the ball out of his feet to get a shot away.

Real substitute Ferland Mendy is then booked for cynically breaking up an Atleti counter.

A change for Atletico Madrid. Former Chelsea captain César Azpilicueta comes on for Nahuel Molina.

Almost for Real! Federico Valverde chips the ball into Joselu who brings the ball down on his chest, but, with his back to goal, unselfishly tees up Rodrygo.

His shot is blocked, but Aurélien Tchouaméni is on to the rebound, smashing his follow-up just wide.

A rare chance for Real as Federico Valverde sets up Rodrygo but his rather rushed volley skids into the side-netting.

Hang on, it was deflected, and from the corner substitute Aurélien Tchouaméni rises highest but heads over.

If the first half was a basketball game, the second is a chess match.

Very methodical, pretty slow-going.

Real Madrid have to change things. Eduardo Camavinga, Fran García and Lucas Vázquez go off.

Ferland Mendy, Nacho and Aurélien Tchouaméni.

Almost 4-1!

José Giménez rises highest to meet the corner, unmarked, and his looping header clips the top of the crossbar.

I reckon Real keeper Kepa just about had it covered.

Antoine Griezmann nearly goes through down the middle but his heavy touch allows a Real defender to scarper back and clear the ball behind for a corner.

Alvaro Morata has got five goals for the season now, no player has more in La Liga.

He's becoming as reliable as a New England Patriots win over the New York Jets.

Rodrygo whips in a corner for Real but it's headed clear at the near post by Axel Witsel.

Real Madrid look stunned. They're keeping possession nicely, but not doing much with it.

We go again.

A change for both sides. Atleti's Koke comes off for Axel Witsel.

Joselu replaces Luka Modric.

The players are in the tunnel. The second half will be with us very soon.

"Serving up goals like a gourmet feast!"

What a line Anthony! This has been a proper Sunday roast of a fixture and it's only half-time.

Anthony: This Madrid derby is serving up goals like a gourmet feast! It's a football spectacle! The excitement is off the charts in this thrilling match.
