Football is a game in which we get to see a lot of abusing, fights and many innocent players.    footytube users shoot

I think nasri is quiet and materzzi or whatever is violent

I think Rooney can get pretty violent when he gets pissed off, for instance England Vs. Portugal, but then again I get that way too during very important matches

I think one of the calmest has to be Kaka, you don't really see him get fired up. Mascherano has got to be one of football's short tempered hot head

Hot heads: El-Hadj Diouf, Jamie Carragher, Kieran Richardson (before), Roy Keane, Ronaldo, etc....
Mr. Nice-Guys: Carlos Tevez, Park Ji-Sung, Del Piero, Steven Gerrard and a whole lot more players....
No offense intended....

Hot head, I think Mr. Gattuso takes the cake, or at least he always looks like it

Vinnie Jones was a hot head. Still is.    Kaka always seems to have a calm demeanor on the field, no matter what happens.

Arsenal's youngsters all look very nice...

Christian Vieri has to be one of the most violent hot heads of them all. The guy took up boxing as a side sports

Grobbelar!    

Fergie and Wenger...

Keane was and still is a hot head right after he was sacked as Sunderland's coach the players told the press Keane would kick and throw things around in the locker room after a poor performance by the team

Ferguson    

Pepe
