Pep Guardiola praised his Manchester City youngsters after coming from behind to beat Bayern Munich 3-2 in America, but he has a big concern over new signing Riyad Mahrez after he went off injured.
Having lost their first games against Borussia Dortmund and Liverpool, City ended their International Champions Cup campaign in style by coming from two goals down to beat the German champions.
Bernardo Silva scored twice in Miami but only came on as a 27th minute replacement for the injured Mahrez, who was taken off with an ankle problem.
Mahrez is Guardiola's only major signing so far this summer, after he joined from Leciester City for a club-record fee of £60m, and big things are expected for the Algerian - who is 20/1 to be named PFA Player of the Year next season after joining up with the reigning champions.
Guardiola did not know the extent of Mahrez's injury when questioned about him after the match, but it is sure to be a big source of concern with the new season fast approaching.
"I don't know. I wasn't in the locker room," Guardiola said after City's record signing. "It was his ankle. We will see, maybe it is not a problem.
"I'm concerned for many things, for injured players, players who are still not here but I am so satisfied for what all of the guys on the tour have done."
City also saw talented youngster Phil Foden limp out of the action with a hamstring problem, after the 18-year-old produced an eye-catching performance for his manager.
“Phil Foden played an outstanding game today, he is a fighter, he is a guy who runs," Guardiola said. "He has an England mentality as in he never ever gives up. But I am so satisfied with all of them.”

City bounce back to beat Bayern
City dominated the opening moments but failed to capitalise on their chances as the German champions' Meritan Shabani opened the scoring after 12 minutes.
Ten minutes later and Arjen Robben doubled Bayern's lead after converting Franck Ribery's pass, and things looked to be getting worse for the Premier League champions when new signing Mahrez was taken off injured in the first half.
His replacement Bernardo Silva narrowed the deficit just before the break, however, and 19-year-old Lukas Nmecha got City back into the game, equalising five minutes into the second half.

City continued to apply the pressure in the second half and Pep Guardiola's decision to name six teenagers for the Miami squad paid off as 17-year-old substitute Adrian Bernabe played a part in Silva's 70th-minute winner.
Speaking after the match, Guardiola spoke highly of his young squad's performance against his former club.
"We analysed our mistakes from the previous games and we played a lot better today. We started really well and had a lot of chances. We kept going and I am satisfied," he told the club's official website.
"We came here with a lot of young players and new players. So for them, it will be good for the future. It helps them to understand the game. I like to see my players fight for our teammates and play like a humble team.
"You cannot imagine how much I have enjoyed these two weeks with these guys. The young guys have desire. They open their eyes and listen because they have their whole career ahead of them. I want to say thank you to them."
