Many hate him because of extra-marital affair that involved girlfriend of former Chelsea colleague Wayne Bridge. He is also hated for racially abusing former Queens Park Rangers defender Anton Ferdinand.
Many hate him for his wild behavior that has made him be sent off-multiple times. It all started in Euro 2004 when Rooney send off resulted to England to be bundled out of the Euros in the quarter finals.
Many say he is loud mouthed and out spoken. He recently apologised to French people after saying in a post-match bust-up that France is a s**t country.
