Arsenal player ratings for frustrating Swansea loss: Gunners punished late on by Bafetimbi Gomis winner

CB: Per Mertesacker – 6

Heart in mouth moment when Montero raced past Bellerin and it was left to the German to stop the pacy South American but was relatively untroubled all night.

CB: Laurent Koscielny – 6

Gave little away and had little to contend with all night. But was outmuscled by Gomis in the air for the Swansea winner
