Sheffield United boss Chris Wilder has claimed the new substitution rule favours more dominant teams in the Premier League.
Top flight clubs discussed the idea of increasing the amount of substitutions that can be made in a game, like we have seen in the Bundesliga, agreeing unanimously on its implementation in England.
The decision mainly came around to help with the sudden restart of football and seemingly an acceptance that players may not be as fit as they were before lockdown. It may also allow young talent to benefit with more appearances from the bench.
Players are also at lesser risk of injury, but Wilder has revealed he is not in favour of the alteration ahead of Wednesday's game against Aston Villa.
He said, as quoted by the Mail: "It favours the powerful clubs. We don't think that is the right way to go about it."
The Blades have been the surprise package of the Premier League so far. Currently in seventh place, the upcoming game against Villa will give them the opportunity to leapfrog Manchester United into fifth.
Sheffield fans may feel well within their rights to dream of Champions League football next season, but Wilder dismissed any talk of continental football, focusing solely on the upcoming match with Villa.
"Are we going to talk about Villa or what? It's the first game up. Is there any chance to talk about that? Because that's all I am looking at. I am not looking at anything else," he added.
"If it gets to the situation where we are one or two games out and we are still in a fantastic position then we will possibly talk about that.
"At the moment we have quarter of a season to go near enough. I am sure that you have seen the fixture list as such as I have seen it, there are some incredible challenges in front of us."
