I've heard maybe 5 different pundits/ex-footballers says that M'Vila has the potential to be the best defensive midfielder in the world (or right up there), so not sure how you can be so sure he's not top class? I don't know myself, just saying that quite a few have said he's extremely good and going to get even better.
I don't know what's going on behind the scenes with M'Vila. Maybe we've bid, maybe we haven't? Maybe they still want top dollar for him? Maybe we were waiting for someone else to come in and set the price, so we knew what sort of financial level we'd have to compete at? Maybe we're not interested at all?
I just doubt the latter is the case, given that we know for certain that we bid upwards of €20M for him last summer.
