The Brazil international joined the R's last summer from Inter Milan, but at the age of 33, he had been tipped to return to his homeland at the end of the current campaign.
However, although his club look likely to be relegated to the Championship, Cesar has suggested that he would strongly consider an offer from another team in the top flight.
"I'm enamoured by Italy, but England has really won me over. I like everything here - the stadiums and the people," he told La Gazzetta dello Sport.
"The supporters are incredible, if a player has the opportunity to play in the Premier League he must go, it is an exciting experience."
Cesar's services have recently been linked with Serie A outfit AC Milan.
