what Suarez does is just on the pitch. It's a sporting crime at worse and for fans he's just like a pantomime villain. Yes, we could do without it but no real harm comes from it.
What Giggs did is just digraceful. Of course, it doesn't take anything away from his football skills and the entertainment he provides in tht regard, but I'd shy away from making him a role model for youngsters... just as much as I wouldn't put Suarez up as an example to follow.
