Toni moved to Roma on loan in the January transfer window and now is expected to make his deal permanent at the season's end.

"Luca's relationship with the club is broken and there is no chance of mending it," Rummenigge said.

"It's up to him and his agent to find a solution in Italy."

Roma are tipped to open talks with Bayern soon over the 32-year-old's future.

Last month, Bayern's honorary president Franz Beckenbauer stated that the UEFA Champions League finalists will bring back Toni once his loan spell at Roma has expired.
