Atletico winger Yannick Carrasco fires in a free-kick which goes past everyone. Everyone bar Marcelo that is, and the Brazilian clears off his line.

Atletico's Diego Godin goes down under pressure from Raphael Varane but no penalty. Think it was the fans rather than players appealing.

Gareth Bale goes flying into a challenge with Juanfran and Atletico have a free-kick in a good position. The full-back slightly bought that.

Atletico Madrid have had most of the ball so far. Real finally get a touch and Cristiano Ronaldo is fouled.

We are under way in the Madrid derby at a boisterous Vicente Calderon.

Who do you fancy to win this match? Are Atletico out of the title race if they lose? 

Should Real have started Lucas Vazquez instead of Karim Benzema?

These clubs are so big that there are streets named after Real Madrid and Atletico Madrid in the suburbs. The two roads actually intersect.

A few stats from Opta before we begin:

Real Madrid have not lost any of their 16 games with Lucas Vazquez in the starting XI (W14 D2).

Atletico have not lost in their last 22 league home games (W18 D4), the best current home unbeaten run in La Liga. 

Real are the side with the most away games in a row without a defeat - 16 (W12 D4).  

Fernando Torres has only scored one goal in his 12 games against Real in La Liga.

Atletico Madrid boss Diego Simeone: "We know that for a long time they were much better than us. Nowadays we compete at the same level as them. As I have explained before, this is just a game, not a complete league. A game is a game and anything can happen.

"We understand that the rival is an important team. They haven't lost in the last 28 matches. They have extraordinary players and that is why they won two Champions Leagues. 

"We will have to move the game to where we feel more comfortable and play with the intensity a game like this requires."

The game could be the last derby at Atletico's Vicente Calderon as they are due to move to the Estadio Olimpico de Madrid in the summer.

“It's a beautiful ground, with beautiful support," said Real boss Zinedine Zidane. 

"Real Madrid players are used to playing at all kinds of stadiums and in heated atmospheres. We are familiar with this ground and we know it's going to be a tough game. 

“It's not only special for me, but the derby is special for every Madridista. It might be the last one at the Calderon. It's special for both sets of fans. 

"People speak about hate between fans and the teams, but seeing this derby is magnificent and I hope we get a beautiful game of football.

“We have to forget the negative aspects, the hate, and have a good time."

A Real Madrid win here would take them four points clear of Barcelona at the top - and nine above Atletico, who are fifth at the moment.

However, an Atleti win would take them up to third, within three points of their rivals.

As well as a derby, this is potentially a big day in the Spanish title race.

Real Madrid leave captain Sergio Ramos on the bench on his return from injury - Nacho starts at the back. Lucas Vazquez starts up front with Karim Benzema left on the bench.

Antoine Griezmann is passed fit for Atletico Madrid after a foot injury and partners Fernando Torres up front.

Atletico Madrid: Oblak, Juanfran, Savic, Godin, Filipe, Gabi, Koke, Saul, Carrasco, Griezmann, Torres

Real Madrid: Navas, Carvajal, Nacho, Varane, Marcelo, Modric, Kovacic, Isco, Vazquez, Ronaldo, Bale.

And now we turn our attentions to the Madrid derby.

What does that mean for the table? Well RB Leipzig are properly top of the table now - after 11 games.

Bayern Munich are second, three points behind the minnows. Dortmund move up to third, another three points off Bayern.

It's over. Borussia Dortmund beat Bayern Munich at home in the league for the first time since 2012.

Oh what a chance. Robert Lewandowski heads wide from six yards out against his former club. Was that Bayern's final opportunity?

We are halfway through injury time. And Bayern Munich break...

Four minutes added on. Bayern midfielder Renato Sanches is booked.

Whistles around the ground. This game has got an edge to it now. We'll have a good bit of injury time.
