We're off again... Can Celtic find a way back?

James Forrest is on but it's a straight swap for Scott Sinclair, who must have picked up a knock.

"We haven't seen Celtic test Barcelona from set-pieces and that's disappointing," chips in BBC Sportsound pundit Alan Stubbs. "It's something that they could exploit."

"I don't think Brendan Rodgers will be too disappointed," says BBC Sportsound pundit Scott McDonald. "Celtic are well and truly still in the game.

"With the way James Forrest is warming up, it looks like he's coming on. Celtic are going long early and there's only really been Dembele and Sinclair up there."

That was Lionel Messi's 501st Barcelona goal...

The visitors are ahead thanks to a nice finish from Lionel Messi. It's not exactly been one-way traffic but Celtic have not been able to offer much in attack. There is still a way back for the Scottish champions and that's thanks to a fantastic save from Craig Gordon. How on earth did he keep that Luis Suarez header out?

Moussa Dembele is working so hard up front on his own. Three Barcelona defenders move to close him down in the penalty area and the ball pings off a few ankles before it's eventually cleared.

Lionel Messi weaves his way in from the right and floats a cross in for Luis Suarez to head powerfully on target from six yards yet somehow Craig Gordon is able to dive across his goal and get a big paw on the ball. A quite remarkable stop.

Celtic get forward and Moussa Dembele twists one way then another before curling a shot on target. It's too close to Marc Andre ter Stegen, although the big German goalie fumbles what should be a routine save before gathering at the second attempt.

Jozo Simunovic is pick-pocketed on the edge of his own area by Lionel Messi and the ball falls for Neymar but the Celtic defender is let off the hook as the Brazilian makes a really poor pass rather than having a lash at goal. 

Barcelona are popping passes around calmly as Celtic pack men behind the ball. When the hosts do get it, they can't keep it for more than a few passes.

Luis Suarez is looking for a foul after jumping into Emilio Izaguirre and he's roundly jeered by the home fans as he does some rolling about on the deck. He's up again, shaking his head, as play rages on.

Classic Barcelona goal. No danger, no danger, no danger - pass, goal. All so quick, all so clinical. The telepathy between Neymar and Messi was incredible. We've seen it so many times now but you never grow weary of it. Celtic fans respond by upping the noise level.

A bad couple of minutes for Celtic there. As things stand, they are going out of Europe with a game to spare.

Plenty of time for that change.

Here comes Jordi Alba again, this time standing up a cross for Ivan Rakitic in a good central area. However, the Croatia international can only nod narrowly wide. Best chance so far...

Celtic eat the ground with a swift counter-attack as Moussa Dembele slips a pass to supporting midfielder Callum McGregor but the ball comes off his heel and Sergi Roberto is alive to the danger, intercepting on the edge of his penalty area.

Barcelona left-back Jordi Alba loves a gallop forward. He gets into the Celtic penalty area and cuts a pass back to Lionel Messi, who can only scuff a first-time effort wide of the far post.
