A huge moment as Real Madrid win a penalty. 

Stefan Savic misjudges his swing at the ball and catches Cristiano Ronaldo rather than the ball. Reckless.

Out of nothing, Isco almost makes it 2-0 to Real. The ball drops from the sky and Isco hits an excellent 20-yard volley which Jan Oblak has to touch around the post.

Atletico winger Yannick Carrasco has a shot from 25 yards out but it's straight at Keylor Navas. We are midway through the second half now.

Atletico Madrid seem to have lost some of the momentum that made an equaliser seem inevitable in the early stages of the second half.

They're still playing well but it's definitely settled down.

Koke and Cristiano Ronaldo square up - and they're both booked. Idiots.

Atletico Madrid boss Diego Simeone is playing real-life Football Manager here. He brings on two strikers, Angel Correa and Kevin Gameiro. Off comes captain Gabi, a midfielder, and forward Fernando Torres, who has been quiet.

Gareth Bale heads over from a free-kick. He probably should have done better. It's a raucous Vicente Calderon after a couple of fouls in recent minutes.

Real have a couple of rare chances in this second half. Cristiano Ronaldo can't get his head onto a cross and Dani Carvajal has a shot blocked.

Gabi has a shot blocked. Atletico Madrid have been excellent in this second half. They're swarming like red and white bees all over Real.

Whatever Diego Simeone has said to his players at half-time seems to have worked. Luka Modric dawdles on the ball for a second and Antoine Griezmann steals it off him and then smashes in a shot from 30 yards which Keylor Navas saves.

Atletico have come flying out of the blocks here. Antoine Griezmann lashes a cross across goal but nobody is there to tap into an empty net. The Frenchman will wish he had shot himself.

Yannick Carrasco almost levels for Atletico Madrid with a brilliant curling effort from 20 yards out. It was only just off target. Keylor Navas mightn't have got his hands onto that.

Atletico have a corner as Filipe Luis' cross is cleared. But Keylor Navas holds Yannick Carrasco's corner.

Atletico Madrid get the second half going. They like late goals so they're not out of this yet by any means.

Cristiano Ronaldo attempted three shots in the first half (all on target), as many as all Atletico players combined (three, none on target).

Neither set of players out on the pitch yet for what could be the final derby at the Vicente Calderon.

In Serie A, Juventus lead Pescara at half-time. Former Real Madrid midfielder Sami Khedira has scored the only goal.

Antoine V: Surely that's not Ronaldo's goal. Looked like it was deflected by a Real player. Suppose cause it's Ronaldo we can let him off

Hugh in France: ... and breathe ... Breathtaking football of unbelievable quality. Isco out of this world
