Araujo is limited on the ball, but the majority of the problems today are coming from having two fullbacks who are extremely limited while in possession and especially in tightspaces. It doesn't give any shortpass exits.
Mingueza is to be expected and you can't expect much more from him in that position. Firpo has been a huge oversight and fooled us all. We would have been infinity better keeping Semedo as converted LB and selling Firpo in the summer (I realise Semedo had his contract situation forcing his exit).
