Only 3 time you can make subs100% a good move , this will restrict diddy teams, wasting more time , looking for balls in the stand, as they use any excuse to waste time .
The Extra subs is a bad move in my opinion as it uses up more time , 10 subs can be made during 90 mins , I bet we don’t see the extra time added on , technically 30 secs per sub , could and should be minimum 5 mins Injury time.
