It's clear the guy is a pitbull and does a lot of dirty work.
It's also clear he's a cheap signing, mostly because his salaries are probably relatively low.
Don't know about his technical skills though. He must be better than Sturaro or be able to naturally play DM when Marchisio can't.
It's definitel a low risk bet. Not sure about the reward, though. If it's also low, I don't like this. But if he shows technical skills enough to put him ahead of Sturaro, it's good enough. Have to wait to judge. If he can be a decent rotation piece (really decent), it's OK.
