Lazio Roma, Italy is the worst one, they had huge flags showing off Mussulini
England, Their top clubs in the premiership all have different races in their teams, pretty much most of them are the best paid ones
Its the 1st and 2nd leagues that make it horrible
Holland, Certain supporters from top clubs while playing against other top clubs it happens, Now in Holland they stop the game for it till they stop, best way to deal with it
