I don't think he is that bad, as seen by some people.
He had very bad luck since he arrived. His injurys have fallen into the times, he was close to get into the team, at Inter and also his injury at Parma, when he was playing quite good.
Now, hes got the problem that his Position is very offerstaffed. the nearest in the way off playing are Gargano and Mudingayi + Benassi, Guarin, Cuchu, Obi.
But I'm sure, he wouldn't have no problems taking the Gargano Part in our game and play it better, like Mudingayi does. So if we take the option for Mudingayi, there is no place for him anymore. But if I think about it: They are on the same level. Mariga is 6 years younger, we paid 10 Million for him, he only gets half the salary of Mudingayi (one of the cheapest in the team), + he can develop.
I'm not sure if it would be that good taking Mudingayi over Mariga. The interest in him is big, and that not without reason and I'm sure he'll prove his worth, no matter where he is playing.
