Di Maria was great in his first season for us, he was very good in the half season he played(missed the other half to injury) his second year, then he got a new contract and was inconsistent in his third season(mou's last). He was inconsistent in the first half season under ancelotti, but then was by far our best player in the second half of the season. Obviously he's not Messi, but he's still a pretty damn effective player overall and when he's on song, he's one of the 6-7 best players in the world.
He was PSG's best player by a mile last season. Dunno what's up with him this season, maybe the rumors that he wants to come back home are true. Would take him back in an instant
