We already packed in the mid (marchisio, khedira, Pogba, pereyra, Hernanes, sturaro, asamoah, lemina) add padoin and we'll have 9 players that are playing there already !
So adding another mid to that roster though he's better than most of them is at least to me a sign that we'll lose a significant player in that position.
Anyways we'll wait and see what's coming in the next couple of months but personally I think Pogba is on his way out and we'd already secured his replacement.
