He got like 3rd in his first season with Juve with a pretty weak side, even though he was fired at the end of his second season the team still got 2nd place.
Finished 2nd place with a weak Roma team.
He's not a world beater, he's boring and not usually able to switch tactics once a match begins, but he's had moderate success wherever he's been. I think he'll keep Inter somewhere between second and 5th.
