Well Khedira is on his way to Everton so I guess it boosts our chances.
Rabiot is actually the best midfielder we can include in a swap. In terms of ability he is good but he just doesnt fit our current idea of football.
Dybala is magic. He is the kind of player that makes you watch football but he is also inconsistent and doesnt appear in the opponent box much. While I admire Dybala and think he has a golden ball potential I also see the chances of him improving us compared to other players of similar value I think we would benefit from getting someone else and improving our midfield so Im all for it.
I just hope we do something as our current teams doesnt scare teams as much as Inter or Milan who have about half our quality
