Pep Guardiola said he was happy with the performance of his new Manchester City side despite a 1-0 defeat to Bayern Munich in his first game in charge.
Both sides were without many of their first-team regulars and Erdal Ozturk's deflected second-half strike was the difference in Guardiola's return to the Allianz Arena after leaving the Bundesliga champions at the end of the season.
The Spaniard has only been working with his new City squad for the past two weeks and said he was pleased with how well his young side performed against Bayern.
"I am so happy, we did many things we spoke about well and in the right moment -- that's why we cannot forget which team we played," he told a news conference.
"In the second half we played with a little more intensity and I'm really satisfied with what we did because we've only been together for two weeks.
"Bayern Munich is always a difficult opponent, but we have to grow and get better. I think we have to play games like against Bayern Munich in order to learn and develop more -- to get better.
"We have many young players in the team and you've seen them here -- all in all, I'm satisfied with what they've shown me."
Guardiola gave a debut to new signing Oleksandr Zinchenko and several Academy players including Spanish full-backs Pablo Maffeo and Angelino, who impressed.
City now head off to China where they will play friendlies against Manchester United and Borussia Dortmund and Guardiola said playing high-calibre opposition will help get his squad ready for the new Premier League season.
"You have to make mistakes to get better -- when you play against second or third division teams you can't see them but you can when you play against quality teams like Bayern," he added.
"They had eight or nine top players and we had a lot of young players on the pitch in the first half.
"We had Maffeo and Angelino who played amazing and of course, Brandon Barker and Zinchenko. We need time and these games to see their level and if, during the season, we can use them."
