Everton boss Marco Silva cannot guarantee keeping Idrissa Gueye this summer.
The midfielder remains a target for PSG after a January move was blocked by the Blues.
Silva said: "I am giving him a little bit of a different role and he is improving and knowing better what the team needs from him .
"He is enjoying his football and he is improving every match.
"Let's see. He is an important player and will continue being an important player but about what can happen in the summer or not, this is something I cannot control but we are really happy with him."
