Yea, at his age, he'd have to be more than decent. Otherwise, his transfer is not really worth it. It's a pointless exchange, except we traded a much younger player.
We probably did it for that trick with the books.
He is better than Arthur.
Arthur is immature off pitch, takes too many touches than passes it simple.
Of course it was in large part for books and because Arthur was showing who he really was and was a player they could use to do it.
Pjanic is painfully slow but would take his style with some give aways than the way Arthur plays.
Just dont think there would have been any real market for him.
