I like the guy's courage and determination, he's a bit of a lunatic but that's alright.
I think every time he steps on the pitch for us, he wants to do too much. He shows the strength of his character and belief in his ability, if not ability. I still think there is a very decent player there, he's technique in possession and his passing are pretty decent and progressive, but he's primarily quite destructive and hard working. He's not quite specialised in either to hold down starting spot, or be central to get best out of him.
I could well see him coming in for some games, just to give us some legs and bite when we are low on numbers and fitness. It might make more sense for someone else to have his place in the squad and have him go out on loan and get settled and playing. He'd be a very good player for a lot of teams on the continent.
I think we can use a player like this in the squad. He doesn't have to be on the bench every match, but he'd be useful for Europa road legs (where we might need to flash some steel), Cup ties, etc. I'd give him at least this season before we move him on.
He may be a maniac, but he's OUR maniac, and damn it he's fun. Plus, I really do see flashes of a genuinely good footballer there.
