Unai Emery is facing a defensive puzzle.
With Rob Holding out for the season, yellow cards to both Sokratis and Shkodran Mustafi against Huddersfield means both are suspended for the game at Southampton on Sunday.
Not only does this give the Spaniard a headache for the Premier League match, but also disrupts his planning for the visit of Qarabag in the Europa League on Thursday.
Thursday’s game would have been used to give Laurent Koscielny and Nacho Monreal a run out. Get 90 minutes of senior football under their belts after long lay offs.
Koscielny would have most certainly started at centre back, with Monreal at left back. The problem now for Arsenal is that with Sokratis and Mustafi now out, the pair are now likely to be our central defensive partnership against Southampton.
So what does this mean for Thursday?
Does Emery continue with the rehabilitation of Monreal and Koscielny by giving them 90 minutes against Qarabagm hope they both get through and hope recover quickly enough for Southampton at Sunday lunch time?
Or does he play Sokratis and Mustafi (injury permitting) against Qarabag, keeping Koscielny and Monreal out of danger for Sunday.
The fear will be against Qarabag, the one of either Koscielny or Monreal picks up a little niggle ruling them out of Sunday. This is highly likely. Small injuries often occur after a long lay off. And even if they do both get through unscathed, are either yet fully fit enough to play 90 minutes twice in less than 3 days?
Arsenal were already without first choice U23 pairing Daniel Ballard and Julio Pleguezuelo, as well as Kostadinos Mavropanos. This would mean that if either Koscielny or Monreal were to not fit for Sunday, either 18-year-old Zech Medly would start, or Arsenal would have to move either Stephan Lichtsteiner or Granit Xhaka into the back four.
Logic dictates that you do not involved Koscielny or Monreal against Qarabag. It would also make sense to not play Sokratis if Mustafi’s hamstring injury is to rule him out of further games.
So Medley and Big Carl Jenkinson it is then/
