They need quite a bit in my opinion. GK, CBs, midfielders. With no CL footy they'll be signing up and coming players though their new sporting director pinched from Dortmund. Will be interesting to see who they appoint as manager though.
Yeah they got GK probs no doubt, but I reckon that and a couple of key other player signings should do it. They must have loads of money to play with, and if the Dortmund dude has already identified who they need and they get a coach who knows how to win shit then they'll be better than this. Wenker lost 13 this season. I can't see them getting worse.
