Hello there and welcome to Eurosport's LIVE commentary of this evening's Champions League Group H clash between European giants Barcelona and AC Milan at Camp Nou.

Alexis runs the ball out for a goal-kick after a Milan pass was intercepted in midfield. The Serie A side running out of ideas early on in this game and it could be a long night for the strugglers if their slack passing continutes.

Xavi picks out Alexis with a delightful pass but Mexes just sticks a toe out to prevent the Barca player from turning goalward and Abbiati collects.

A fine angled pass from Messi finds Xavi in the Milan's danger zone but the Spaniard's touch is too heavy. All Barca so far.

Abate is warned by the referee as he drags down Neymar - the defender has been involved in a couple of late tackles so far and he's fortunate he hasn't been booked yet.

Robinho breaks away as Milan look to hit their opponents on the counter-attack but he's eventually dispossessed. What sort of impact will the Brazilian have tonight?

Kaka showing his years of experience as he draws the foul from Neymar, just to relieve his side of some pressure.

Milan deal with the corner but the ball is played back into the box in the direction of Neymar who can't control the pass and Abbiati gathers.

Barcelona coming forward dangerously through Messi who plays a delightful one-two with Xavi but he just loses his balance at the vital moment. Moments later Busquets' deflected effort wins the home side a corner.

Messi steps back and lets Xavi try his luck. The maestro's effort lifts over the wall but is dragged wide.

Barcelona's Neymar wins a free-kick after he was caught by Nigel de Jong. Dangerous position, the only question is, who will hit it?

Tonight's clash is the pair's 15th duel in the Champions League and is the tournament's most frequent match.

And we're off. If Barcelona can pick up the three points tonight they will secure qualification into the last 16. If Milan win, they will level points with the Spanish giants.

The bookmakers clearly feel a win home is inevitable judging by the odds for this match. Barcelona 2/9; Draw 6/1; AC Milan 14/1

Massimiliano Allegri (AC Milan): "We will have our chance if we play well defensively, like in the first game against Barca. For the manager, the challenge is to have a better game than the one at the San Siro. How is he (Messi) not playing well? It’s not true. He’s on form, that’s what we saw in the last match. He’s dangerous and he’s still the best in the world. We’ll have a tough time if we don’t pay any attention to him.”

Pre-match manager comments - Gerardo Martino (Barcelona): "I think that this must be the third news conference in the last five days and more or less the 20th question about Leo's situation. And I will continue saying exactly the same thing. What I am is happy to have him, to be able to coach him and have him in the team. Let's wait for the next match and see whether he continues to contribute what he has been contributing to Barcelona, when everything he does is decisive in the match."

Taking recent form out of the equation and the statistics are still firmly stacked in the home side's favour tonight. Barcelona have won their last two Champions League home games against AC Milan, scoring seven goals in the process. The visitors have won only three of their last 16 Champions League away games and only one of their last 11 Champions League away games in Spain.

Barcelona top Group H after three games with two wins and a draw. AC Milan currently occupy the final qualification spot with one victory and two draws.

Milan, on the other hand, have had a disappointing season thus far having just picked up five victories from 16 games and they currently sit 11th in Serie A.

Although there has been some criticism about Barcelona's early performances, there can be little argument about their recent record - they have 13 wins and four draws from 17 matches this season.

Messi has only netted 12 goals in 17 so far this season. For any other forward, bar Ronaldo, that is quite an impressive record. But not when you consider he had scored 21 goals at the same point last season and 20 the year before, you can see why alarm bells are ringing in some parts of Camp Nou. Messi hasn't scored in his last four games and if that barren run continues tonight, you can only imagine pressure will continue to grow on the forward.
