Bernd Leno
Along with Ainsley Maitland-Niles he was at fault for Barcelona's equaliser and had to be bailed out by Willock when he over-committed. Made some good saves though. 4
Ainsley Maitland-Niles
After such a good first half this was a real Jekyll and Hyde game for the young right-back. The awful own goal was just the tip of a disappointing iceberg for him this half that saw his usual strengths going forward nullified. 3
Callum Chambers
Barcelona appeared to find him out in the second half, drawing him slightly out of position to create space around the box. Was almost as at fault as Shkodran Mustafi for Luis Suarez's winner. 4
Sokratis
After taking a knock he seemed to find it harder to keep up with the game but was still the strongest part of Arsenal's back four defensively. 6
Sead Kolasinac
Gave Arsenal a better option than Nacho Monreal had in the first half. Provided more solidity in defence and was more of a threat going forward. 6
Granit Xhaka
Was far tidier in the second half and he helped to organise things while Arsenal were under the cosh at the start of the half. 5
Joe Willock
Frustrated Barcelona throughout, was a threat going forward and a real thorn in their side in defence. His goal line clearance with Leno beaten was a particular highlight. 8
Henrikh Mkhitaryan
Did next to nothing before being subbed off in this half. 4
Mesut Ozil
With Arsenal spending most of the time defending while he was on in the second half there was not much for Ozil to do but he tried to creat chances to get forward when he could. 6
Matteo Guendouzi
Looked tidy early on in the half but as Barcelona took tighter control he went missing more often than he should in such an important position. 4
Pierre-Emerick Aubameyang
Wasn't able to create the same threat he did in the first half but still worked hard and was unlucky to have a golden chance stolen from him by Gabriel Martinelli. 6
Arsenal substitutes
Dani Ceballos (on for Willock)
Gave fans a scare when he was fouled heavily by Lenglet but was able to get back to it and provide a calming influence to the midfield while others were panicking. 6
Gabriel Martinelli (on for Ozil)
Stole a dream opportunity right off the boot of Aubameyang and didn't do a whole lot else. 4
Bukayo Saka (on for Mkhitaryan)
Worked hard and was a much-needed creative spark for Arsenal going forward as Barcelona tried to put their authority on the game. 7
Eddie Nketiah (on for Aubameyang)
Worked hard but wasn't on long enough to make a difference. N/A
Lucas Torreira (on for Xhaka)
Put himself about and made some juicy challenges to let Barca know he was there but not on for long enough to make a difference. N/A
Shkodran Mustafi (on for Mustafi)
With only four minutes on the pitch he shouldn't have been on long enough to make a difference but was caught fast asleep and out of position to let Suarez in for the winner. 3
