The 44-year-old has accepted that die Roten must spend big money on players, despite the Bavarians' earlier claims that they will not break the bank for the Spaniard
The Bavarians start the new Bundesliga campaign on the back of two trophyless seasons, and have been widely tipped to sign midfield reinforcements as they look to reclaim the title from Borussia Dortmund.
Javi Martinez, as well as Bayer Leverkusen's Lars Bender, has been linked with a move to the Allianz Arena throughout the summer, but Bayern have maintained that they are not prepared to meet the Basque side's asking price.
However, Sammer has now hinted that a formal bid for the Spain international could be imminent, with the start of die Roten's league campaign on the horizon.
"Right now, we're not doing it because it's crazy," Sammer mused to Kicker. "But if we want to do things on the pitch, then we must be crazy."
Bayern have already added the likes of Mario Mandzukic, Claudio Pizarro, Tom Starke and Dante to their squad this summer.
