Yes, a big change. But judging based on last couple of weeks, I think Barcelona are not as bad as they used to be. Offensively, they improved a lot and credit has to go to Koeman. From a defense point of view, they are bad, but they can only solve that by buying new players. Garcia is coming, so maybe he solves a little bit of their problems. I think Mingueza is alright and better than Umtiti and Lenglet. If De Jong plays as a CB, they might already have their back 3 sorted out or at least it is much better than their current line up with Lenglet
