Suarez is a very good player, but he's not as special as many people seem to think, I think his abilities are overexaggerated....he's no Zidane, Bergkamp or Henry and thus I'm not sure all the baggage and risk he brings with him is worth the hassle (especially when you consider the price tag attached to his name).
If he does this sh*t again he'll end up with a longer ban and his club will end up losing a key player for 3/4 of the season.
