8. Wayne Rooney vs David Moyes
Rooney felt so let down by his former Everton boss that he made a number of allegations in his book ‘My Story So Far’ claiming that he felt Moyes was too overbearing and controlling. Rooney also felt that his confidence was betrayed when a private conversation was leaked and that facilitated his frosty exit to Manchester United. The two were forced to clear the air last season when Moyes was appointed United boss, but neither could do much to stop their season turning into a disaster.
