I think I would be slightly more bothered than 'not overly' if Wilson were to be sold, but I get what you mean... I also get what folk are saying about King's attributes and on his day he can be awesome and unplayable, however, we've not seen many of those days this season...
Also, Wilson wins far more or our goal kicks than King... For whatever reason, be it strength I don't know, King never seems to be able to back into his defender and win the ball, seemaingly favouring an aerial battle with the defender, whihc more often than not, he loses.
At the end of the day, there is something wrong/unbalanced about our squad currently, and this summer will be a defining period in our ability to remain a PL team...
