Pep Guardiola has played down reports that Lionel Messi could sign for the Champions League holders, stating "the club doesn't run that way".
The club splashed out on Mario Gotze and Thiago Alcantara during the summer but according to the Bayern boss, a move for Messi would be too much for the "shrewd" nature of Bayern's spending.
When asked about the prospect of signing Messi, the Spaniard told reporters: "[Bayern president] Uli Hoeness surely would never offer to spend a fortune to sign Messi.
"Bayern Munich does not work that way and the player is happy at Barcelona."
The two struck up a great friendship during Guardiola's stay at Barcelona and won 14 trophies together, establishing the Catalan side as one of the greatest of all time with their success.
Despite struggling to hit top form in recent weeks, Bayern have won four of their first five games and currently sit second in the Bundesliga table, behind Borussia Dortmund.
Bayern kick off their Champions League title defence at home to CSKA Moscow tomorrow.
