The Germany international has revealed the Spanish giants are interested in signing him.
“Barca have the best team in the world and I am honoured that they are seriously interested in me,” Toni told La Gazzetta dello Sport.
“I am still under contract, I know, but Mario Gomez is about to arrive from Stuttgart and he is an extremely good striker.
“We will have four strikers next season and that is quite a lot.
“I am not sure if I will be staying at Bayern and I will definitely have to talk to the club about this.”
AC Milan and Inter Milan are also reported to be interested in signing Toni.
