That's one prime example of Roman's thin-wearing patience on top class managers. Either that, or the expectations of the club are ridiculusly high (which, to be fair, they are). If Carlo's credentials were available to the footballing world (i.e. he had no club, but had the tactical mettal to just go to any club and promote them) I bet a club like West Ham would break the bank to aquire his services. The point I'm making, is rather than stick with a manager, who enjoys managing the club, despite not winning anything in a season, and quite a large chunk of that season goes tits up, Roman just disposes of them like worn out sandpaper. They look good once they first start out, then when there's any sign of wearing out, it just gets chucked. I don't think Roman understands the true meaning of "the long run". If a manager is kept at a club for long enough, he will understand the setup more. He will understand the type of players to buy every summer/January period. He will understand the formations to pick every week, and he will learn to take responsibility of the players regarding their performance.
