Beaten by decent header from Fabregas but will feel he was left far too exposed. Impressive stops late on to deny Alexis and Neymar.
LUSTIG (6) Coped admirably with the pace and trickery of Neymar. Booked for a foul on the Brazilian near the interval which restricted him in the second period.
VAN DIJK (6) Relatively solid. One good block from a fierce Xavi effort and got forward occasionally. Bulk of his night spent stemming the flow of constant Barca attacks.
AMBROSE (6) One shimmy past Neymar drew a roar of appreciation and couple of decent interventions, but will feel he should have been much closer to Fabregas as Barca finally broke Celtic's resistance.
IZAGUIRRE (6) Few chances to get himself forward. Lucky, perhaps, only to be booked for reckless challenge on Bartra.
MATTHEWS (5) On hand to help Lustig cope with Neymar. Had one glorious run that ended with a mis-kick out the park. Slack in possession, but not the only one.
BROWN (4) Constantly on the move and solid defensively in the middle until that moment of madness. His straight red for taking a fly swipe at Neymar left Celtic with it all to do.
MULGREW (6) Set-plays a little disappointing. May feel he should have done better with a header shortly before Barca took the lead.
SAMARAS (8) Tough shift for the Greek forward as Celtic chased shadows for much of the game. Worked his socks off.
COMMONS (6) Covered just about every blade of grass. Tracked back to offer cover as Celtic hassled and harried Barcelona whenever their opponents had the ball.
STOKES (4) Found it difficult to hold the ball up and keep the pressure off.
KAYAL (4) On for Lustig as Celtic tried to compensate for the loss of their captain.
FORREST (5) Barely on when he had the chance of the night. Pounced on van Dijk's knockdown and drew decent stop from Valdes.
PUKKI (5) On for final five minutes.
