Bayern Munich chief Hasan Salihamidzic is coy over their pursuit of Liverpool striker Sadio Mane.
Bayern have so far failed with three offers in the last week for the wantaway Senegal star.
Salihamidzic has refused to be drawn into the saga surrounding the 30-year-old, instead pointing to the Bavarian club's other attempts to recruit a new ace.
"We're working on several options in attack," he said. "The transfer market is not easy, it always depends on the financial possibilities of the club.
"I don't want to talk about players of other clubs."
He went on to add: "Of course we can't rely on one option to strengthen our attack. We must have several options."
