Oh, you've just used that stat. I thought you might know something.
I've seen plenty enough of Wickham over the last couple of years to know he's a good striker, with the potential to get a lot better.
Is Leo going to get better at his age? Probably not.
I reckon they are very much comparable right now, and likely to move in opposite directions moving forward - thus a swap worthy of consideration.
Comparing them right now, Leo is probably better in the air (although Wickham IS a big strong bloke, too), but Wickham is MUCH quicker, which is something the Albion team desperatley needs, imo.
