Elneny has been one of the better performers of late, relatively speaking of course. So the bench is inevitable. Ramsey, meanwhile, has been off form all season. Hence the start. Ox has been better in the centre, so he's wide. We won't really play 3 at the back, not with Monreal in the line up. Dropping Bellerin is the ideal response to his recent problems. Should smash the kid psychologically, a Wenger speciality.
