Mendy, 23, returned from a serious knee injury for Manchester City in April, meaning he has played just seven games this season.
But the four-time France international believes he will be ready for the World Cup, which begins in mid-June, if he is picked.
"I'll do like everyone else and try to get as much playing time as possible," Mendy told SFR Sport .
"We'll see when the [squad] list comes out.
"Physically and mentally, I'm at full power and I'm ready to go to Russia."
Mendy has become something of a cult hero at the Etihad Stadium, after his hilarious antics on social media.
