Bayern Munich fear Pep Guardiola already has one foot inside Manchester City.
The Sunday Mirror says the German giants were stunned last month when Guardiola turned down their offer to make him the highest-paid coach in the world when the Spaniard told them that money was not his main motivation.
Bayern chief executive Karl-Heinz Rummenigge was forced to abandon a plan to announce a new two-year deal for Guardiola at the club's AGM on Friday night.
City WILL make an official approach for the world's most-wanted manager once they are cleared to do so.
The Etihad club have insisted that reports in Spain that they have already done a deal with Guardiola are premature.
