Vaguely related - but I read yesterday (please don't shoot the messenger) that Sharp got married in 2010, and his young son who tragically died was actually conceived with his mistress (now his girlfriend). Apparently his wife only found out that he was expecting a son as the whole situation was unravelling last autumn.
Its a bit easier to understand why he turned us down last summer then, and his situation was also probably a big factor in moving to the South Coast (i.e. as far away from Yorkshire as possible) in January. Of course, football reasons would have influenced his decision too, but people forget sometimes that footballers are human beings with lives and their own intricacies outside of the game.
