Pep Guardiola knows he needs to improve the squad, if he wants to reach his target of winning the Champions League with Bayern.
One major gap has appeared in the right-back position, with Rafinha proving he is not good enough to compete with Europe's elite.
Recent reports linked Bayern with Matteo Darmian from Torino, while other shocking rumours suggest Guardiola could go after Sergio Ramos.
The Spaniard is reportedly unsettled at Real Madrid, but heavily linked with Manchester United. However, Pep might use his Spanish connections to lure him to Germany.
On the wings, Antoine Griezmann and Angel Di Maria remain the most prominent names linked to the German giants.
While Griezmann has a £47 million release clause at Atletico Madrid, Manchester United want to recoup the £59.7 million they paid for Di Maria.
Either player would probably be a great steal by Bayern, who are looking for long-term replacements for their ageing stars, Franck Ribery and Arjen Robben.
In central midfield, Inter's Mateo Kovacic is the latest star linked with Bayern. Inter are reportedly keen to sell one of their young prospects in order to finance their heavy spending spree this summer.

With such powerful options on the wing, Thomas Muller, Mario Gotze and Robert Lewandowski would probably compete for the striker's role.
