Champions League-winners Bayern Munich are open to new investors, CEO Karl-Heinz Rummenigge has told a sports sponsorship conference in Duesseldorf.
Two German brands currently have shares in Bayern's Aktiengesellschaft -- stock company -- which operates the football club.
Adidas and car manufacturer Audi each hold 9.1 percent of stocks, with Bayern Munich e.V, the registered club, holding the other 81.8 percent. Adidas acquired its shares for 77 million euros in 2009, and Audi invested 90 million some seven years later.
And Rummenigge said a third investor could join them, telling the conference: "We could sell further shares -- I wouldn't entirely rule that out."
However, he did rule out any extra investment being spent on players, explaining: "We don’t need money for transfers. We will not buy a Messi. We will invest in the infrastructure -- in stones, not in bones."
Insurance company Allianz, which has the naming rights to the Allianz Arena for a further 17 years, could be another potential partner, but Rummenigge said: "I've also heard those rumours but, at the moment, I can’t confirm them."
