Pep Guardiola's reign as Manchester City boss started with a 1-0 defeat in a friendly at his former club Bayern Munich on Wednesday in a game watched by 68,000 fans.

Erdal Ozturk scored the only goal of the game in the 76th minute although both sides were under-strength and under-cooked at the Allianz Arena with many of the leading players enjoying longer summer vacations following Euro 2016 and the Copa America.

Belgian international Vincent Kompany was an unused substitute for City after recovering from the thigh surgery which kept out of the Belgium team at the Euros.

"I had a special feeling -- it was like coming home once again," said Guardiola who has been replaced at Bayern by Carlo Ancelotti.
