Carrick is excellent at picking out a pass (or atleast he used to be). It's a shame he didn't play more for England, they could've really used him. Cleverley definitely should stay for another season. He's content atm with a squad role, and is an academy import. Plus, I honestly don't believe he's as **** as last season made him out to be. He may never be world class, but I believe he can still do the job for us. Anderson should go, he was a Number 10, who never completely became a CM, and ended up being average. Can do better than him atm.
Actually, Ronaldo wasn't exactly a nobody before he came to us. Fergie himself said in his autobiography that Madrid were already sniffing around him. Carvalho, on the other hand, is just fresh off his first breakaway season (where he's experienced excellent success, no doubt). But the price is pretty high for him (Release Clause), and as such, it is visible as to why people are reserved about him (Especially since our last Portugese import Bebe turned out to be a flop.
I didn't mention anything about before he came to us (although he was still rather unknown lets face it), but my point is.... everyone is a nobody before they become a somebody.
LVG needs someone like him for his system, it's something we just don't have right now. It's a gamble of course, but realistically he's going to be something good, virtually everyone connected with Portugal rates him.
Who are the other alternatives? Benders break up play, mentioned them before, Khedira... could he do it? Possibly but he's not the same player after that ligament injury it seems. Vidal..... be prepared to empty the bank.
