Bayern Munich chief Karl-Heinz Rummenigge says they won't pay "crazy wages" to tie Robert Lewandowski to a new deal.
The Poland striker has been linked with Real Madrid, Manchester United and Liverpool this summer.
"We have had a number of meetings with Lewandowski's agents. We are ready to renew his contract," Rummenigge told Bild.
"We will definitely not sell him. But we have always been willing to change a player's contract if the situation or his value changes.
"We will not be paying the kind of wages on offer at Manchester City and Paris Saint-Germain, though. We are paying some very good wages, but those clubs are paying crazy figures.
"You do not win more trophies [by paying such wages] anyway."
