England U21 boss Stuart Pearce is against the new Premiership ruling of seven substitutes.
"If the new rule stops players going out on loan, it's definitely a bad thing," Pearce said. "You have to look at the pros and cons. On one hand Premier League managers are going to have more options when it comes to making substitutions, but the downside is you're going to have young players who will hardly ever get to play."
"Managers will be taking 20-man squads to away games next season," Pearce said. "There will be 11 players on the pitch, seven on the bench and two in the stands in case of emergencies. We're going to have players who are doing nothing. It's something that has to be addressed.
"At City I had calls all the time from other managers who wanted to take my players on loan. Managers are going to be more reluctant to say yes now. The size of some of the squads is going to be frightening."
