Dybala is a brilliant player but he's playing in a team that runs roughshod over its league; his performances in Serie A need to be taken with a grain of salt. He scores a lot of goals from the spot as well.
Obviously I'd take him in a heartbeat and to be honest I think United spent their £89m on the wrong Juve player, but for me he's not on Hazard's level yet. If, however, you asked me who the better player was at the same age, that's a much better question. I may be more inclined to lean towards Dybala, since Hazard didn't have his dominant season for Chelsea until he was 24 and Dybala is 23.
