It's not really necessary Mike, the transfer fee had already covered the costs.
Do you think Anichebe/Fellaini's combined wages would be enough to cover Robles, Kone, and McCarthy?
Also, the retirement of Nevile, Mucha and Hitzelsperger being released would have freed up wages.
It does seem the case to me, that the actual net investment is close to nothing. It's not a complaint.
Matt - Because it's not guaranteed. It's a possible fee
