Wonderful tackle by Casemiro to deny Ferran Torres. Pedri clips a ball over the top to Torres, who looks like he's about to open the scoring before Militao dives in to block his shot.

For anyone who doesn't follow La Liga closely, Barcelona are much improved under Xavi - and with a few good winter signings too.

That side who looked like they might finish mid-table under Ronald Koeman earlier this season are a thing of the past.

First booking of the game as Real midfielder Toni Kroos goes in studs up on Sergio Busquets.

Harish Lakka: Real Madrid are all over the place. Barca is a better team than PSG. They can not only win this game, but also win it comfortably.

Barca admin impressed by a Ronald Araujo tackle on Vinicius Jr.

Rodrygo has two shots blocked on the edge of the box for Real. Plenty of chances so far.

Oh we have another one now and it was almost a beauty. Ferran Torres pounces onto a loose ball outside the box and curls it just wide. Thibaut Courtois was diving and very worried.

No shots for three minutes now. Boooooo.

Luka Modric takes a free-kick quickly and Real find Vinicius Jr in the box but his shot from an angle is saved by Marc-Andre ter Stegen.

Both keepers have been involved early on.

Two great saves from Thibaut Courtois but Pierre-Emerick Aubameyang should score for Barca.

Ferran Torres runs down the right and pulls it back for Auba who shoots straight at the keeper from 10 yards out.

Barca keep the move going and Ousmane Dembele's curling effort is saved by a diving Courtois.

Barca striker Pierre-Emerick Aubameyang slides in and catches Toni Kroos on his shins with his studs. Another player lucky to avoid a booking.

Barca try to get the ball away three times but Real win it back each time. Ousmane Dembele, not the most popular Barca player anyway, lets Luka Modric slide in and take the ball off him. Luckily for the visitors it ends in a Barca throw.

First save of the game as Vinicius Jr beats Ronald Araujo this time before pulling it back for Federico Valverde, whose first-time shot from 20 yards is clawed round the post by Marc-Andre ter Stegen.

Real winger Vinicius Jr looks at the referee in disbelief as Ronald Araujo nudges him over but the whistle doesn't go.

Barca have put Araujo, more of a centre-back, on the right to deal with Vinicus' threat - and have left Dani Alves on the bench.

Real's first chance as Federico Valverde glides through the centre from his own half before finding Rodrygo on the right. The Brazilian beats a defender but hammers a shot into the side-netting.

Real Madrid are playing without a recognised striker today in the absence of Karim Benzema. Rodrygo plays a cross-field ball from the right but can't find a team-mate.

This is the first Clasico at the Bernabeu not featuring Lionel Messi or Cristiano Ronaldo since 10 April 2005.

The free-kick is played into Ferran Torres, who flicks the ball into the air and then hooks a volley miles over the bar.

There's a foul in the opening 12 seconds as Ferran Torres goes past Eder Militao who takes him out of it. I've seen yellow cards for less.

We are under way. Real Madrid are playing in black and Barcelona are in yellow.
