Wantaway Bayern Munich striker Robert Lewandowski has had his head turned by his agent, according to the Bundesliga champions' sporting director Hasan Salihamidzic.
Lewandowski last week confirmed that he has informed Bayern he will not be extending his contract beyond the end of next season when it is due to expire.
The Poland international stated after the final game of the season against Wolfsburg that he had not received a proposal for new terms.
However, Bayern chief executive Oliver Kahn insisted on Saturday that was not the case, with a "concrete offer" being tabled to his agent.
Salihamidzic has now accused Lewandowski's representative of talking his client into a move away from the Allianz Arena, where he has spent the past eight seasons.
"He got an offer. I don't know what the agent said to his player, but we definitely made an offer," Salihamidzic told Sport1 on Sunday.
"We had a conversation with the consultant and said very clearly how we imagined the future, with a very clear sum and terms.
"He has an advisor who has turned his head and has turned it all year round. It's not clean."
Reiterating earlier comments made by Kahn, Salihamidzic vowed Bayern will not look to sell Barcelona-linked Lewandowski in the upcoming transfer window.
"Robert has a contract until 2023 and he will fulfil it," he said. "We have the greatest respect for Lewy. FC Bayern have always behaved correctly."
Lewandowski has scored 50 goals in 46 games for Bayern in all competitions this season, making him the top scorer among players from Europe's top five leagues.
That is the second-most the 33-year-old has managed across his eight years in Bavaria, behind the 55 he netted in 2019-10.
While questions will inevitably continue to be asked about Lewandowski's future, Manuel Neuer looks set to extend his stay with Bayern.
Like Lewandowski, the Germany international's contract has just over 12 months left to run, but he is reported to have been offered a one-year extension on top of that.
"I'm very optimistic. Manuel is one of the keys to success," Salihamidzic said. "Please be patient, but we're on the right track. We're on the home stretch."
