cmonurz Bit of a pointless argument this without clarification of the actual laws, but for me, no, that full minute should not be added on. It's part of the game. Do we add another 30 seconds if an attacking side take ages over a set-piece? Or if there are successive corners?
So why is 30 seconds added on for each substitution???
Oh and for the record the ref does add time on if player time waste
