Welcome to LIVE text commentary of Barcelona's trip to Rayo Vallecano in La Liga. Kick-off 20:30 (UK time).

The referee blows up full-time with Mascherano still receiving treatment. It's been a rout - Rayo Vallecano 0-7 Barcelona.

Mascherano's in a lot of pain after a clean challenge from Michu.

There will be two minutes of added time.

That puts Messi level with Cristiano Ronaldo at the top of the La Liga top scorer standings. Who's your money on?

GOAL! There's the seventh! Pedro tees up Messi and the Argentinean slides a cool finish to take his league tally to 43.

Credfit to the Rayo fans, they're still in fine voice despite the scoreline.

That's Pedro's second of the night and fifth in the league this season.

GOAL! And it's six! The corner's half-cleared but only to Messi, who finds Pedro inside the box and the 24-year-old fires past Cobeno.

Montoya pushes forward from the left full-back position and earns Barcelona a corner.

Barcelona host Malaga in their next game, while Rayo travel to Mallorca.

Rayo corner. Michu rises to meet it but heads over.

Mascherano slides in with an excellent challenge to thwart Michu's run.

Michu attempts to bring down a long cross-field pass but can't get enough on the ball and it goes out for a throw-in.

BARCELONA SUB: The visitors make their final change, with Alexis replaced by Tello.

Alves and Thiago celebrated that goal in typically Brazilian fashion with a little dance but Puyol quickly came over to the duo to put an end to that. There's not a lot to celebrate at Barca at the moment, even if they are winning 5-0.

GOAL! And it's five! Alves whips in an axcellent cross from the right and Thiago heads the ball into the ground and past the keeper.

Barca are happy to keep possession, knocking the ball around in defence while looking for an opening further forward.

This is the 15th time this season that Barca have managed to score at least four in a game.

Rayo have lost six of their last seven league games (10 goals scored, 17 conceded), though their win was also their biggest-ever in the top-flight (6-0 vs Osasuna).

BARCELONA SUB: Afellay comes on for Busquets.
