Sissoko played alongside Remy at Newcastle United in the Premier League last season after the striker joined on loan from QPR.
Remy, 27, proved to be one of the bright notes in a turbulent season at St James' Park, ending the campaign with 14 goals in 26 top-flight appearances.
The former Marseille man has struggled to replicate such form on the international stage so far, having scored just four times in his 22 appearances for France.
"Loic (Remy) fits in very well in this group," he said. "He is a player who lives well, who gets along with everyone.
"It's true that he has had less time playing with the French national team than his club. But it's completely different.
"Everyone has confidence in him. We know he can bring something, create danger at any time. I hope we will see a big Loic Remy during this World Cup."
