Former Chelsea midfielder Michael Ballack has suggested Pep Guardiola lacked "trust in the club", backing the Spaniard's decision to join Bayern Munich next season.

Ballack's comments follow similar sentiments from former Chelsea coach Ray Wilkins, who claimed the ruthless approach of owner Roman Abramovich is putting potential manager's off moving to Stamford Bridge.
Having played for Chelsea from 2006-2010, and calling Munich home for four years prior to that, Ballack believes Guardiola made the right choice by ending his year-long sabbatical to become part of the Bundesliga.
"If you want to work as a coach for longer term you need consistency, trust in the club and also the environment around the club," Ballack is quoted as saying in The Sun.
"Maybe that is a point why he didn't sign [with Chelsea]. But it is also a big challenge as a coach. It's a fantastic signing for Bayern and for Pep Guardiola as well.
"Nobody in Germany expected him to sign. It shows the Bundesliga has grown a lot in the last few years and his decision looks like it's not all about money, he is a coach with a philosophy.
"He needs a good environment and will find this in Munich. There is a good atmosphere, that was a big reason to sign."
Following Guardiola's announcement last week, there has been a flood of messages from Barcelona players and coaches supporting their former boss' decision.
