Pep Guardiola did not get the dream start he would have preferred as Manchester City coach having lost his first game in charge as the Citizens were beaten 1-0 by Bayern Munich at the Alianz Arena.
Guardiola opted to parade a string of younger players in his squad, but the youngsters created minimal chances across the 90 minutes.
Erdal Ozturk scored the solitary goal in 76th minutes when he sent a shot from the edge of the box past substitute keeper Angus Gunn with a deflected shot to earn his side victory in their second run-out of the summer.
Guardiola named a largely inexperienced side for his first outing, with Aleksander Kolarov, Fernandinho and Fernando proving the only real experience in the starting lineup.
City’s only attempt of in the first half came via the boot of Kelechi Iheanacho, but his effort cost no hassles for Sven Ulreich who simply watched the ball sail onto the roof of his net.
Guardiola brought on further experience for the second half by introducing Gael Clichy, Fabian Delph and Wilfried Bony, while hero of the first half Caballero was replaced by youngster Gunn in goal.
After a rather ding-dong affair, Bayern finally put themselves in front 14 minutes to the end of regulation time as Erdal Ozturk saw his effort deflected off Clichy and getting the better of Gunn between the sticks to condemn Guardiola to a losing start on his new job.
