I don't think anybody has been particuarly cruel. Fact of the matter is that him/his wife, and father for that matter, seem to have very thin skin and can't handle any criticism. He's in a cut throat world, and he's been paid in the region of £20 million in the last 4 years by our club and scored 17 league goals. Do they really expect universal praise for him? They're either very naive or just complete tits. Anybody who isn't consistently good for 10+ years will get criticised by somebody at some point. Dom has been consistently good for about 12-18 months so any stick he's had is par for the course really.
Can some criticism go over the top? Of course, but that's the world he's in, and he's been paid handsomely for it. I don't hate him as a player, I always try to back anybody as long as they appear to try, but he's not been good enough for 4 seasons now.
