"There's all this talk about Cristiano Ronaldo and Gareth Bale and if they like each other, but you can see the difference tonight. Bale takes people away from Ronaldo... without him, Atletico can afford to have two players on Ronaldo."

We go to the last 45 minutes of the tie. All to play for.
Just over half an hour played in the Championship fixture between Reading and Birmingham. Very little at stake. No goals.

"That's the best opportunity by far. He should have scored, it was a good save though. Atletico gave the ball away in midfield, that's unusual."
The chance of the game! Atletico Madrid keeper Jan Oblak denied Gareth Bale in the first leg and he produces a very similar save to spring from his lien and save brilliantly from Cristiano Ronaldo.
Atletico gave it away level with the 18-yard box, James Rodriguez picks out Ronaldo with a lovely first-time pass and Ronaldo sidefoots one at Oblak. A good save, but you'd bank on Ronaldo to score.

"Javier Hernandez is working hard and buzzing around but Real still haven't created an opportunity."

Peter in Darlington: Shane Daly, are you mad? Two set piece goals AGAINST Atletico? Never going to happen!

There's definitely a red card in this game in the second half.
Naren Ramachandran: Reply to Eduardo from Brixton. Chelsea do it against teams like Sunderland. Atleti doing it against Madrid in UCL semis.
Real have completed 270 passes to Atleti's 132 so far. The pattern of play is set.
Colin Todd: Atletico always get good value for their yellow cards.
They do indeed Colin. Much like your son Andy if memory serves...
Image source, ReutersAtletico commit men forwards in numbers for the first real time but the ball in from out wide is not up to scratch. Cristiano Ronaldo is the latest man to go to ground too easily. Stay on your feet.

"The tempo is playing into Atletico's hands. Real should make full use of the multi-ball system and when the ball does go out of play, try and catch one of the Atletico players off guard."
Fernando Torres is on the bench for Atletico Madrid tonight. He's still a hero in Madrid and you wouldn't rule out him having an intervention in this game. Forget his spell at Chelsea. He has.

It's a fair point Eduardo. I guess Chelsea can't often claim to be underdogs though. Does that make a difference?
Eduardo, Brixton: When Chelsea defend like this they get slated. When Atletico do it, everyone laps it up.
