I saw an Arsenal fan actually worry about their fixture run-in (4 home games to bottom six sides including Villa; Sunderland; and their rivals City), so that tells you what shape Arsenal are in that the fans worry about bottom clubs, home games and teams with the same points as them.
But let's say they beat Norwich and Villa and lose at City, Man Utd would still need to win all their games, and Leicester and West Ham won't make that easy. So you would expect Arsenal to stumble through yet again, but 4th being a UEFA Cup spot would be a hilarious swerve of karma.
