That's a crap comparison. It's very different situations.
Next season Wilson will probably be better than them. But he'll be on huge wages and will have pretty much zero sell on value in 2-3 years time. I bet he goes on a free to the Championship.
There's a chance in a couple of years we are able to sell Bakwa or N'Doye for decent money and I bet they will be/are on much lower wages than Wilson will get at Leeds.
