Mario Gomez's agent has confirmed that a number of clubs have shown interest in his client.
With that in mind, Ferber has insisted that the former Stuttgart centre-forward would have options should he opt to leave the Allianz Arena during the summer.
"There were always expressions of interest in the services of Mario," Ferber told Bild. "They were during his years at Stuttgart, right before his move to Bayern Munich, and right ahead of his most recent contract renewal. But also right now at this point in time."
Gomez's contract with Bayern does not expire until 2016.
