The France international is likely to feature this weekend against Spurs, who are just one of the sides credited with an interest in the player who spent last season on loan at Newcastle United.
"I never talk about different players," Pochettino is quoted as saying by BT Sport. "I know Remy because he is a good player, an international player.
"But, yes, he is fast and we need to be ready in the game on Sunday because he is a very good player."
Meanwhile, Remy's teammate Danny Simpson has backed the player to stay at QPR.
