Pep Guardiola may not have trusted Chelsea - Michael Ballack

Former Bayern Munich and Chelsea midfielder Michael Ballack believes that Pep Guardiola's decision to move to the Allianz Arena next season instead of Stamford Bridge may have been down to a lack of "trust" in the people and environment at the London club.

Guardiola left Barcelona in 2012 after a successful spell in charge and is currently in New York on a sabbatical, but the 41-year-old had been tipped to make a return to the game at one of several English clubs.

Ballack thinks that the signing of Guardiola illustrates how the Bundesliga is growing, and says that the atmosphere and set-up at Bayern will have influenced Guardiola's decision.
