5 subs makes sense that is virtually half the team which would benefit from getting some rest, all teams, yes even those with small squads (you can say it works to the big clubs with big squads but just think of the chances it can give at smaller clubs to young players, come on as a sub turn a game and bang you get the chance you need in the first team). Two more players in a squad will make a huge difference further down the season when tiredness really starts to hit the smaller clubs if they think there is an increase in injuries and niggles now just think how much worse it will be come Jan/Feb time. Most managers are calling for it and even UEFA have taken it on board so why are the Premiership powers not, clearly it is for selfish reasons, just as the charge for PPV games.
