The reason why Bale was made an enemy in the press was to deflect from the glaring problems with the team and the rest of the squad, players that have strong relationships in the press and walk around in an armour suit when it comes to deflecting any criticism or problems. When he's gone, certain people won't have another "Bale was watching golf on his mobile phone!" article to hide behind.
The pre season has been mostly terrible but it's basically just Bale, Bale, Bale, Bale. The sooner he's out, the sooner the uncomfortable questions get asked, and none of them have to do with Bale.
