Bernd Leno
Had very little to do in the opening 45 minutes, but what he did do was done tidily without any real cause for concern among his defenders. 6
Ainsley Maitland-Niles
Provided some of the brightest moments going forward for Arsenal so far with surging runs down the right and ocassionally cutting inside but couldn't quite find a finishing pass. 7
Callum Chambers
Didn't have much to do but was fairly tidy and was never really at fault when Barcelona did manage to get into good attacking positions. 5
Sokratis
Let Antoinne Griezmann know he was there early on and remained his solid usual self out of possession, looked a little unsure passing out from very deep. 6
Nacho Monreal
Found out on a couple of occassions by Nelson Semedo and had to be bailed out by both Joe Willock and Reiss Nelson. 5
Granit Xhaka
Didn't do much except give away an unnecessary foul when Arsenal were on a promising attack and wildly misplace a pass to let Barcelona in for their first real chance. 4
Joe Willock
Appeared to be absolutely everywhere on the pitch, helped out going forward keeping moves going and tidied up repeatedly in defence, especially with one last ditch block from Dembele. 7
Henrikh Mkhitaryan
Kept fairly quiet by Jordi Alba but did draw the Barcelona left back into a couple of silly fouls and a yellow card. Also gave Maitland-Niles a good pivot to work off. 6
Mesut Ozil
Picked out the perfect pass for the opening goal and kept the game moving forward in the early stages when Barcelona seemed a little unsure of themselves. 6
Reiss Nelson
Started brightly down the left hand side and had Semedo in bother both going forward and in defence but faded as the half wore on. 6
Pierre-Emerick Aubameyang
Was a constant source of running for the youngsters in the side to latch onto, a little wasteful early on but grew into the game quickly and scored an absolute rocket to give Arsenal a deserved lead. 8
