Both managers feel it is unnecessary to have water breaks in the middle of the first and second halves.
It is a practice that has started since the league resumed after the COVID-19 lockdown, along with five substitutes instead of three.
Asked if these breaks should be permanent, Guardiola told reporters: "No.
“I think we did it because of the lack of preparation for all of the teams, with just three weeks before the start of the competition and maybe for the weather conditions
"The managers use it to talk to players, of course."
Moyes agreed, telling reporters: "Personally, I don't think water breaks should have been introduced.
"I understood why they were, but I thought it should've been at the referee's discretion in games – if the temperature were up in the 70s or the 80s [Fahrenheit], and they felt that players needed a drink.
"I don't think they're a necessity and it's also a change of rules from where we were at the start of the season. I think it's wrong to start the Premier League season in one way and finish it in a different way."
