only becasue the linesman said "it was deliberate!"
leaving the ref no choice
if u watched the replays with souness and shearer afterwards you can see both sides
from the linesmans view it was a clear cut decision no questions,
but when you look at it from the tv camera s angle you can see it wasnt intentional so a 4 match ban is a bit harsh, although i still reckon (according to the rule book too) that it should have been a red coz you're not even allowed to raise your arm are ya
