Pep Guardiola admitted Manchester City lost belief when a goal up during their capitulation on Sunday against Leicester City.
Riyad Mahrez had given his side an early lead but Guardiola bemoaned a nervousness among the hosts as they failed to convert a dominance in possession into a second goal.
City conceded five goals at home for the first time in 20 years and the defeat serves as a significant early blow to their title aspirations.
‘We didn’t create much and started to think we weren’t playing well,’ Guardiola said.
