I know most people disagree, but I reckon there's a lot to work with when it comes to McKenna. Naturally left footed and decent on the ball, which instantly raises the price of a centre half these days. Strong in the air, a threat at set pieces, physically big.
He might not improve much, in which case he'd be a waste of money for that lot, but they're in a position where they can take a risk that way. I don't think he's ever going to be brilliant as such, but I don't agree that he's the utter diddy many make out.
Hopefully everyone else is right and they spend a fortune on him and he fails.
