Riyad Mahrez sustained an injury against Bayern Munich

Manchester City manager Pep Guardiola was in the dark over the extent of the injury sustained by Riyad Mahrez in his side's 3-2 win over Bayern Munich in the last game of their International Champions Cup campaign.

City secured victory after fighting back from two goals down against the Bundesliga champions, however, the win was soured after their new £60m signing from Leicester City was taken off injured in the first half.

Speaking after the match, Guardiola said he did not know about the condition of Mahrez, who joined the club earlier this month.

"I don't know [the extent]. I wasn't in the locker room. It was his ankle. We will see, maybe it is not a problem," he said.

"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."

Having already faced two defeats in their first games against Borussia Dortmund and Liverpool, City dominated the opening moments, but failed to capitalise on their chances as Bayern's 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 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 game, the Spaniard 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."
