He is what he is, I don't think anybody thought he was gonna come in and stroke players egos. He's not that man, but to be honest, nobody knows what he's gonna fetch to the table at United. If soem fans are expecting him to challenge for the PL title then that's their problem, they're just living in a fantasy world.
I don't think one defeat to Swansea will be a reflection on his ability, especially with the players he has to work with, particularly defenders.
A lot of you boys were commenting on how refreshing it was to hear Di Canio stick your players through the mangle in post match interviews, maybe some of United's players could do with that treatment?
I'm not worried at all, to answer your question... my only worries are with Ed Woodward and his inability to get deals done quickly.
