because teams are about morale, shared success.
We are in a new era, we don't need a fat prick like Rooney acting like a 5 year old (I really like him as a footballer but can stand this kind of petulance)
It just needs 1 high profile footballer to ruin his own career in his best years and others might think twice. Ruin his year, make him fat, make him miss the world cup.
