Arsenal v Cologne: Predicted Line Up – The return of Jack Wilshere and how many youngsters will get a chance?
Defence – Rob Holding, Per Mertesacker, Calum Chambers
This is one that could see a lot of different combinations. All three of these players could come in but it would not be a shock to see Wenger play Shkodran Mustafi or even stick with Nacho Monreal.
Laurent Koscielny is suspended but the defence could be made up of any combination of the other five players.
Mertesacker seems the most concrete selection and Rob Holding should start next to him. It just remains to be seen if Chambers sees his first action of the season or Mustafi gets more playing time.
