Hello and welcome to LIVE coverage of Barcelona’s clash with Roma – a fixture that will evoke memories of Alessandro Florenzi’s Puskas-nominated wonder-strike in the reverse clash in Italy.

POSSESSION: Barca 80%-20% Roma

CHANCE! Another huge hole through the middle as Busquets picks out Messi but the little Argentine hits his shot just wide. He scores those more often than not.

Barcelona have let in only one goal in their last seven matches with five clean sheets in a row.

Barcelona have it in the back of the net as Suarez squares to Messi. The flag is up. Ooh that looked a tight one!

Well this looks like a long evening for Roma already. If this pattern continues, we’re looking at 5-0.

CHANCE! Barca flood forward again, so lovely to watch already. Cracking effort from Messi on the edge of the box and a super one-handed save from Szczesny.

Neymar wins Barca a first corner. He takes himself but an easy clearance for Pjanic. so much space for Barca suddenly but Neymar wanders just offside

Very odd to see Neymar with his short haircut as he draws the first foul inside the Barcelona half. Back it goes as Barca build from the back. Roma in their change strip of all white.

KICK-OFF: Referee Cuneyt Cakir blows his whistle to get us underway here. Barcelona setting up 4-3-3, Roma likewise.

FIVE MINUTES TO KICK-OFF: The players are lining up on the pitch and the Champions League anthem is being played. Not long to go now.

TEN MINUTES TO KICK-OFF: Roma have conceded six goals in the opening 30 minutes, more than any other team in this season's Champions League.

Roma have not won away from home in the Champions League in their last seven games, alternating between draws and losses in those seven games (D4, L3).

Rudi Garcia, Roma coach (via Uefa): "Football is a beautiful game and it is not always the best team who wins – I don't believe any team is invincible. If we don't believe we are worthy of playing here, we are going to lose. We have to take our chances and work hard. We know Barcelona will have the ball most of the time, but we have to make the best of the opportunities we get. We cannot defend throughout the entire game, because then we will lose."

STAT: The reigning champions are unbeaten in their last nine home games against Italian sides, winning seven and drawing two in that time.

Luis Enrique on Lionel Messi's return: "He is back fit and this is a joy for us - to see the greatest player back again and now we get to enjoy him. Messi is fully recovered, he is already in the right frame of mind and his injury is forgotten. He has to recover his muscle tone and his form, but you have to play to recover that."
