He only gets into trouble if he gets sent off the pitch...Sharon could pick on Rebecca Loos because she was not a big star, she would never pick on David an A'Lister....Just as she would never have picked on Kylie the way she picked on Dannii.
presumably, since we are lead to believe sharon`s comments were because of her `friendship` with the beckhams, that might have had more to do with her not picking on david. dannii was no saint at the x factor either. she was quick to speak about the feud between them in her book, but she didn't admit what annoyed sharon about her. that being, the situation where dannii was sleeping with the boss and generally behaving like teacher`s pet.
