I apologise for the sarcasm.
The truth is that Fellaini is/was a vastly overrated, defensively suspect, non creative midfielder who is worth nowhere near 28 million pound. And it was ridiculous the way that some Evertonians (who have been able to recognise his limitations for years) were subjected to abuse and derision by those who thought he was some kind of amasing central midfielder.
Look at the United forums, they can't stand him, and they think he is a slow, defensively suspect, non creative lump, who is nowhere near United standard. And they are correct.
His best position is without question behind the striker, and he is worth about 20million pound, but I would be absolutely gutted if Everton spent 20million on a player like Fellaini.
McCarthy is far superior.
