It was always going to be a huge summer for Niko Kovac's men after it was revealed that both Franck Ribery and Arjen Robben would be moving on and would need replacing.
Add to that the fact that Bayern opted against turning James Rodriguez's loan spell from Real Madrid into a permanent deal, it was clear new attacking reinforcements would be needed to be able to compete in the Bundesliga and in Europe.
Manchester City winger Leroy Sane became the number one transfer target of the summer but there were immediate concerns over whether or not Bayern would be able to get a deal over the line. Kovac appeared confident it would happen, the powers that be not so. The valuation that City placed on the Germany international, thought to be close to 100million euros, appeared to be beyond Bayern, who said on more than one occasion that the fee would have to come down. There were also question marks over whether City wanted to sell and whether Sane wanted to move back to his homeland despite his lack of regular action with City.
However, all the 'will he or won't' he came to an end last week when the player picked up a long-term knee injury, meaning a move will not happen before the September 2 deadline.
In addition, Bayern failed to lure Callum Hudson-Odoi - also out injured at the moment - away from Chelsea. However, they cannot be blamed in any way for not striking a deal as the Premier League outfit, under a transfer ban, simply refused to sell.
The hope had always been to sign young, talented forwards, but it seems Bayern have reverted to Plan B of older, more experienced forwards.
Croatian international Ivan Perisic has just arrived on loan with a view to a permanent move, while there is talk fellow Croatian and former Bayern striker, Mario Mandzukic, could return to the club.
The arrival of the former has failed to excite the fans, forcing Kovac to come out and defend the signing and it could take something bigger to appease the Bayern faithful.
There is talk a loan move for Barcelona star Philippe Coutinho could happen.
But again they may lose out to Paris Saint-Germain, who want him as part of a swap deal for Neymar, while the press suggest Coutinho would not fancy a switch to Germany - news that will cause even more angst among the Bayern fans as the deadline fast approaches.
Bayern have dominated domestically but have struggled to compete for the Champions League in recent seasons.
The lack of spending so far has raised concerns among the fans that another early exit from Europe's elite competition will be on the cards again in 2019/20.
