(CNN) -- Bayern Munich have placed an enormous 150 millon euros ($198.94 million) price tag on midfielder Franck Ribery.
Ribery played a key role in Bayern's title success last season.
The French international star was linked with AC Milan as a possible replacement for Kaka if he had opted to go to Manchester City.
Ribery, who plays a similar playmaking role to Kaka, is also a reported target for other leading clubs in Europe during the January transfer window.
But Bayern general manager Uli Hoeness has set the bar high for any bidders.
"If Kaka is meant to be worth 120 million (euros) then Franck Ribery is worth 150 million," Hoeness told Eurosport television.
"We would only perhaps start to consider selling him at a sum like this," Hoeness added after Bayern's 2-0 friendly win at second flight Kaiserslautern on Monday night.
Ribery, signed from Marseille at the start of the 2007/08 season, helped them to the German title in his first season.
Bayern went into the Bundesliga midwinter break in Germany trailing surprise leaders Hoffenheim on goal difference as they chase a second straight title.
The Munich giants had Italy World Cup star Luca Toni and American Landon Donovan on target in the friendly win which came after they returned from a two-week training camp in Dubai.
Earlier on Monday, they agreed to let unsettled German international striker Lukas Podolski go to Cologne, but will retain his services until the end of the season.
The Bundesliga resumes at the end of the month after its traditional six-week break, which will controversially be shortened to three weeks next season.
