Footballer likes biting people

[Napoléon]

This guy didn't bite off the ear of the undisputed heavy weight boxing world champion.

You clearly don't know how much of a beast Branislav Ivanovic is

But fair point nonetheless.

A psychiatrist told me biting is an expression of a persecution complex, resulting from a sense of weakness and inability to defend oneself using normal means.

That's actually pretty interesting. Suarez is always moaning about the press in England getting on his back, and he does seem to have a definite persecution complex.
