4. Angel Di Maria
This might be a bit of a 50-50, Di Maria didn’t really do much for Manchester United during his one and only year at the club, but he did start his career really well. Unfortunately, he was working under Louis van Gaal and that didn’t really help much.
Di Maria was shipped off to PSG where he has found his scoring boots and has done well for the Ligue 1 club. A Real Madrid star couldn’t perform at Manchester United or was it that he wasn’t given the room and space to perform under Van Gaal, we will probably never know.
