5: Luis Suarez
The feisty Uruguayan had the world at his feet when he moved to Liverpool, and only a slight reputation as a controversial figure.
Fast forward to current day and Suarez is undoubtedly the most detested footballer in the world, and there isn't much he hasn't done when it comes to inspiring the hatred.
Biting players, consistently diving and using foul play to get one up on opposition teams are just some of the things he is known for.
Even Liverpool supporters can't back his credentials as a decent human being and, aside from being a very good striker, there isn't much to him that you can find yourself liking.
