The Brazil goalkeeper, on loan at MLS side Toronto, could return to England for next season, with Harry Redknapp's side a play-off win away from promotion to the Premier League
The Brazil international linked up with former QPR defender and now Toronto coach Ryan Nelsen in February, joining the MLS franchise on a temporary deal having fallen behind Robert Green in the Loftus Road pecking order following the club's relegation from the Premier League.
It was understood that Cesar would remain abroad until December but it seems he may be back in England ahead of the new season, with QPR now just a play-off win over Derby County away from a return to the top flight.
"It depends on the World Cup. Queens Park Rangers wants me in August. I don't know what will happen," Cesar explained.
"I’m contracted still in England for a few more years. I'm contracted to return there in August after the World Cup. I can't really give you a clear answer as to what my fate is after the World Cup.
"I've always been a professional person. Even if I win the World Cup, I'm going to keep to my word, return to my [parent] club and help them win championships."
A more pressing issue for Cesar is undoubtedly the World Cup, with the former Inter shot-stopper set to join up with his Brazil team-mates in midweek.
Luiz Felipe Scolari's men have been drawn with Croatia, Mexico and Cameroon in Group A and Cesar admits nerves are beginning to set in ahead of their opening match against the Croats on June 12.
"I'm very anxious," the former Inter No.1 confessed. "It’s getting close to the time to meet up with the team and start on this important journey.
"The whole country is obviously preoccupied [with protests and strikes] but we hope things get settled before the World Cup.
"Every World Cup is a big opportunity; they all have their own flavour. This one being in Brazil is even more special for me.
"It's my country, my family is there and I just have God to thank for the opportunity to play in this World Cup."
