That's true, but regardless interested parties will look at the quality of the teams he's played against and that will impact their offer.
We can tell ourselves that Aberdeen, Hearts, Killie etc are quality opponents, and maybe they are on a good day, but compared to other leagues the quality of opponent just isn't there. He can score as often as he likes against Auchenshuggle Wednesday, but it isn't going to impress that many people is it?
He can be a good player, but I don't think the case has been made to call him a great player. And the red cards don't help either.
