Owen Hargreaves believes Bayern Munich are the only team that can stop Manchester City winning the Champions League and a famous quadruple.
Pep Guardiola's side are still fighting on four fronts after progressing to the quarter-finals of the European competition with a 4-0 aggregate victory over Borussia Monchengladbach.
City also have the Carabao Cup, the FA Cup and another Premier League title in their sights this season.
While Guardiola has played down City's chances of winning all four trophies, Hargreaves thinks they have a strong chance of doing so and claimed the only team who can stop them in Europe is last year's winners of the Champions League.
