The Brazilian number one has been seeking a move away from Loftus Road following the Hoops' relegation to the Championship, but neither Arsenal, Napoli nor Villarreal followed up their apparent interest by making a formal bid.
Reports claimed that Fiorentina were the closest to signing Cesar, but the former Inter Milan keeper turned down a return to Serie A despite wanting first-team football in a World Cup year.
However, Fiorentina's sporting director Daniele Prade has insisted that those rumours are untrue and that they did not make an offer for the 34-year-old, partially due to his wage demands.
"We were never rejected by Julio Cesar because we never contacted Julio Cesar," Prade told La Nazione.
"For two reasons - Julio Cesar has not played a real match since last April and then he has a very high salary, too high for us."
