With Premier League survival nearly secured, the Eagles' sights have now turned to offseason recruitment.
The Frenchman enjoyed a fruitful spell on loan with the Black Cats in 2015/16, in which he made 40 appearances across all competitions and he says he is open to a return to England.
"I'm only 27 years old," he told SFR Sport. "I signed with Saint-Etienne until June 2019. "I am very happy there and I think only about football, about being on the pitch. My agent takes care of the rest.
"I spent an amazing year in Sunderland. [The Premier League] is the best championship in the world. Why not [return to England]? Only God knows if I'll be at Saint-Etienne next season. For the moment, I do not know.
"With the board and the coach, we are dreaming of qualifying for Europe. On May 19 [after the season has finished], we can sit around a table and discuss."
