First team stars such as Kevin De Bruyne, Sergio Aguero, Vincent Kompany, Ederson, David Silva, Gabriel Jesus, Raheem Sterling, Kyle Walker and John Stones have not made the journey to compete in the annual International Champions Cup pre-season tournament with most not expected back until a week before the start of the domestic season in England.
An undermanned City kicked off their pre-season with a 1-0 loss against German side Dortmund at Soldier Field in Chicago on Friday.
Manchester City have revealed their new away kit, recalling one of the most famous games in the club's history.
Pep Guardiola says Manchester City are yet to decide whether youngsters like Phil Foden and Brahim Diaz will leave on loan.
And he said afterwards: "It was nice to see my old team-mates".
"It was really good for their futures because we played one of the best teams in Germany and we did many good things". "The courage, intensity and desire to play was very good".
"I know it is not easy for him what happened in the last period, but he's with us and tomorrow he's going to play". We can not forget what we've done but we start again. We missed the ball in some situations and they used the counter-attack.
"I just wanted the team to do well", added Hart who still harbors hopes of an global return. Luke Bolton, a young winger, made his first start as a makeshift right-back and battled hard while inside him, Brazilian Douglas Luiz was in the holding midfield role he failed to nail down during a season-long loan at Spanish side Girona.
"We will try and find a solution".
"Riyad played good in the first game", Guardiola said.
"It will be a good experience for them [the young players] to realise they can compete [at senior level] and play well". We of course prepared to win but it's normal (not to win games) in this part of the season - it just prepares the team.
