Manchester City boss Manuel Pellegrini admits star duo Sergio Aguero and Vincent Kompany may miss the Premier League kickoff.
Pellegrini knows they will have less than two weeks to get fit for the start of the Premier League season.
Arsenal, City's opponents in the Community Shield in 10 days' time, have already written off some of their key players for the big kick-off and Pellegrini may have to do the same.
He said: "The five players who arrived last Thursday, Hart, Milner, Yaya, Silva and Dzeko, I think that they will be ready for the Premier League.
"We will with see the rest of the players who arrive next Monday. Can they be fit in 15 days? Maybe not all of them will do it.
"We are trying to prepare our team in the best way. We've had a very good pre-season with part of the team. We had another five players playing some minutes today. The rest of the squad arrive next week we are preparing well for the Community Shield and Premier League.
"We have a very good squad but this pre-season we have a lot of players who cannot play. We're happy with the squad, not only the team. That's why it's important for all these players to take their chance when they get it."
