Manchester United boss Jose Mourinho says every player in his squad will get a chance to play.
The Red Devils are involved in four competitions this campaign and will need depth if the Portuguese is to rotate his squad.
Midfielder Paul Pogba did not feature on Sunday but is expected to make his debut when United host Southampton on Friday.
"Paul Pogba is very good, he's a phenomenal player. Our idea is that he will be a very important player for us," Mourinho told BBC Sport.
"In August it can be frustrating for players not in the team, because it's one game a week.
"But in September we have the League Cup, the Europa League starts and there's international games. It's a real marathon and then there's space for everyone.
"That's why we have such a good squad.
"I met a sad squad in my first day, a squad not happy with their situation. But I found immediately a team who want to work and win matches and titles, as well as making fans proud."
