Yeah, but it's not very precise. If one club can give him "some" control over the transfers, and the other club gives him more, what does it mean? There is no in between, there is no "some" or more. It is either you get controll, or you get none. What Mancio has is illusional, because he might get some, but if Moratti is putting his hand down, he will get what he want's and in that case Mancio has no power, as it is. So it's all relevant.
And basing on that assumption, Jose has not much to gain in that department, no matter where he goes, and he must know this.
In Spain for instance, the presidents are offering players when ellected for cry out loud, no matter what the coach wants.
He would gain total acces only in England, he would like that in Italy or Spain too, but it's not how things work in Latino countries.
Sure, one club can offer more(at some degree), but I think there are other more important factors he would take under consideration. From what I got from him, the most he wants is total support of the club, and confidence in him, as well as the goal, that the club wants to be the best.
We are really in very good position, and loosing this guy will be like crashing your new Ferrari just before reaching the insurance headqaurters.
