Robert Lewandowski has asked to leave Bundesliga champions Bayern Munich, sporting director Hasan Salihamidzic said on Saturday.
The record-breaking striker wants a new challenge at the age of 33 after eight years with the Bundesliga giants.
His intentions had been mooted in recent days but have now been confirmed, with Salihamidzic telling Sky television the Poland international has made his position known.
In response, Bayern have told Lewandowski he remains under contract until the end of next season.
It means there could be months of uncertainty ahead as Lewandowski seeks to leave and Bayern look to convince him his future remains in Munich.
Barcelona have been strongly linked with a move for the striker, but their head coach Xavi would not be drawn on Lewandowski when he spoke on Saturday.
Salihamidzic explained his conversation with the player, who hit a record 41 goals in last season's Bundesliga.
"He said that he would like to do something else. But our attitude hasn't changed: Lewa has a contract until June 30, 2023. That's a fact," Salihamidzic said.
"I spoke to Lewa. In the conversation he told me that he did not want to accept our offer to extend the contract and that he would like to leave the club."
Salihamidzic declined to entertain the question of what might change to alter the stand-off, saying: "I don't deal with that because our stance has always been clear."
The announcement regarding Lewandowski came in the minutes before kick-off in Bayern's final game of the season at Wolfsburg.
Predictably, he scored in the 40th minute to take his goal tally to the season to 50 across all competitions.
