The Gunners could be set for more transfer disappointment as the Brazilian international admitted he'd be keen to talk to the Portuguese giants.
Currently on the books at Queens Park Rangers, the Brazil number one wants regular first-team football in a top-flight European league heading into a World Cup year.
He's reportedly been told he can leave Loftus Road for the right price. Arsenal were strongly linked with the 33-year-old, especially after Wojciech Szczesny's less than convincing display on opening day at the Emirates Stadium.
The Gunners had initially cooled their interest in Cesar after the Super Hoops priced Wenger out of a move and it became clear the former-Inter stopper was after a big pay day.
But the report claims they were recently considering another move for the keeper as Wenger has come under increasing pressure from his own supporters following the nightmare 3-1 defeat to Villa.
But they may have left it too late as Cesar has revealed he'd be keen to discuss a move with the Portuguese club.
"Benfica are a big club and I am proud to have been associated with them," Cesar said as quoted by The Metro.
"I will speak to my agent to learn exactly what is going on. I only like to talk when things are concrete."
