Despite such perceived failure, Sir Alex is more than wary of the threat posed by Carroll and has predicted a difficult night for United's defenders, though the boss admitted he'd never spend an estimated £35million on a player of such limited experience.
I think its up to the boy to improve himself, Sir Alex told. I think he only played something like a dozen games for Newcastle and then he had to deal with a £35m transfer to a club like Liverpool when hes young. Its quite a big jump for him you know.
Id certainly not sign that kind of player for that kind of money. Weve gambled on young players in the past, maybe a couple of million or whatever, but when you get that level - £35m you really have to do a bit more homework and see how he is in his second season maybe.
Its not a lot of games that hes had. Hes a big lad, a great header of the ball, aggressive and is a big bugger. You know hell be a handful for defenders for us on Wednesday.
