Yeah. If you know the answer just please say. For some reason i've got it in my head that it could be 2, but i'm more than certain its 3. I take it by your response though I must be stupid and it's plainly obviously 3.
3 points for a win was used by Football league in 83/84 season (York first team to get 100+ points). World Cup used it first in 1990 and Euros used it first in 1996 here in England.
