Problem is Pochetinno has always liked to crowd the middle and get his width from fullbacks. He can't do that with the fullback options they have now because they're all average, bar Rose; whose old and might leave anyway.
I'm not as bothered too much by Dybala going there as such, it's more them moving in those circles that bother me. He's obviously a great talent, but I think he's also a lazy little shit that plays when he wants. I don't think he'll like England and the PL much at all either.
Come on Arsenal, start moving so we can all stop talking about Tottenham.
