I don't feel as though they're overpaid, but I'd rather they actually got fined every time they demonstrated inapparopriate behaviour. So many people, of all ages, watch football, and to have players headbutt each other, pick fights, shout vulgar insults and slur swear words at each other is just rediculous.
If they're going to be paid that much, they should live up to their responsibility as celebrities and behave in an acceptable manner.
Obviously not all footballers are like this, but it gets beyond a joke when they headbutt each other over a tackle.
