Ange should talk to Sir Alex to get a heads up with subs changing a game….I think he was trying to make the point that if the team isn't locked in and competing, the subs won't matter. Personally, I found this a bit odd as I thought the reason you introduce subs, aside from injuries, is to make tactical changes or shake up the energy and change the flow when your side is under the cosh.
1999 Champs League Final Utd won off the back of his two subs goal v Bayern ,Sheringham and Solskjaer ,
A coach worth his salt takes no better pleasure than winning a game due to the introduction of a substitution when game is getting away from them…..its called earning your corn.
