Yannick Carrasco has got his dancing shoes on. He tricks his way into the box before going down under the attentions of Casemiro.

He had already laid the ball off though really. It would have been a soft penalty to award.

Stefan Savic goes into the book for the hosts after hauling down Isco.

Toni Kroos's delivery from the free-kick is sublime, picking out Casemiro whose header is parried by a Jan Oblak in the Atletico goal.

This has been a humdinging start.

Atletico Madrid are cranking the volume notch a little higher.

Yannick Carrasco ghosts by Marcelo like he is not there and floats a lovely cross into the near post.

Koke's volley on the stretch is palmed away by Keylor Navas. He had to be sharp.

Fernando Torres heads into the ground and over the top from the resulting corner.

Real's Danilo has his name taken by the referee after a poor first touch means he attempts his second by waving his studs around Filipe Luis' nostrils.

Antoine Griezmann is urged to shoot from 30 yards and he does not need asking twice.

A little too much adrenaline and not enough control on that one. It flies well over.

Diego Simeone waves his side forward from the sidelines.

They are not going to die wondering.

This might be a running theme.

Sergio Ramos is rolling around on the deck claiming to have copped an elbow from notorious hatchet man Fernando Torres.

He has survived.

It is Turkey's Cuneyt Cakir on the whistle tonight.

He blasts on the acme Thunderer and we are up and running.

Jeers for every Real touch, cheers for every Atleti involvement.

Thomas Hollern: I've always said the ''old firm'' derby is THE DERBY but recently it's not lived up to the hype. Celtic have been too dominant 

A banner has been unveiled opposite the entrance to the players' tunnel - which reads 'We are proud not to be like you'.

It is Atletico Madrid's fans saying that everything that Real isn't is what they strive for.

The teams are out. The Champions League jingle is done. 

It is almost time.

The Vicente Calderon is jammed to the rafters and, for many in the stands, jumping.

We just await the teams...

No other news in Madrid this morning.

While they go hammer and tongs on the pitch, in the boardroom there is a non-aggression pact between Real and Atletico.

The two have long had a gentleman's agreement not to pursue each other's players.

It has been tested to the limit this week with Real Madrid putting the final touches on a £20.1m deal for Atleti full-back Theo Hernandez,, external who spent the season on loan at Alaves.

Apparently Real have not technically broken the agreement as they have activated Hernandez's release clause rather than putting in a bid that Atletico would have to take a decision over.

Now, Antoine Griezmann's contract has a 100m euro (£85m) release clause...

Can you see where this one might be going?

Spanish newspaper El Pais, external is reporting that a coach containing Real Madrid fans was attacked as it approached the Vicente Calderon, with at least one supporter injured by bottles and stoned being thrown.

This is still an unconfirmed report but there are some pretty convincing pictures doing the rounds.

These two have previous.

Zinedine Zidane and Diego Simeone were the big beasts of the 90s and 00s midfields around Europe, one all art, the other all graft.

They played each other eight times, with Inter-and-Lazio era Simeone coming out on top with four wins two draws and two defeat on his record.

Cristiano Ronaldo scores goals at a rate that seemed to have disappeared with Dixie Dean.

He drops jaw-dropping stats almost as regularly. 

Here is a pearler.

The Portuguese's hat-trick in the first leg means that he has scored 103 goals in the Champions League, three more than Atletico Madrid in their entire history.

This was the scene that greeted Atletico Madrid's players when they left their training session at the Vicente Calderon last night.

No side has ever overturned a two-goal first-leg defeat in the UEFA Champions League semi-finals, never mind find the three unanswered goals that Atletico need to turn this tie around.

But there is a template for Diego Simeone's side tonight: 7 February 2015.

Real Madrid were top of La Liga, came to the Vicente Calderon and were dispatched 4-0 by the hosts with Antoine Griezmann and Saul Niguez on the scoresheet.

It is however the only time in the past four decades that Atletico have beaten Real Madrid by three clear goals at home.

It's going to be tough.

This is Real's last visit to the Vicente Calderon. There is a huge incentive for Atletico to pull off a famous comeback.

Atletico need three goals but there is no doubt that Real's defence is not too sturdy.

It is a night where the hosts must be bold and chase the game.
