I was in the same boat. His Chelsea stint was not great and the fit is a bit questionable at Arsenal. But, going for young players that showed great potential (e.g. Ødegaard, Jesus) is paying off. So if he can add depth and competition to the first team, it might be worth the price.
That seems wildly overpriced for that player. How are Chelsea robbing Arsenal blind like this? I mean, his record in the prem league isn't exactly fantastic. I sure hope he proves me wrong.
Hoping Mikel sees something in him that seemingly nobody else does. Feels like such an expensive transfer to have focused on, hey ho, here we go though.
