The 33-year-old is eager to seal his place in the Brazil squad ahead of the 2014 World Cup and has been heavily linked with a move to the Gunners
Hoops boss Harry Redknapp indicated recently that the Brazil international would be allowed to leave, rather than spend the season prior to the 2014 World Cup in his home nation playing in the Championship.
Arsenal have been heavily linked with the 33-year-old, and Cesar has now fuelled speculation that the Gunners are among the clubs pursuing his signature.
"There are indeed talks with some teams, but nothing definitive,” he told Globo Esporte. “This is the Confederations Cup moment, I have to focus on doing a good work for the national team.
"I won't name the teams as it would not be ethical since I am under contract with Queens Park Rangers. I let people responsible for my career deal with it."
Cesar is in the Brazil squad for the Confederations Cup and could be in the side to face England in Rio on June 2.
