The Belgium international signed for Roberto Di Matteo's Chelsea side during the 2012 January transfer window, but remained with Racing Genk, his club at the time, until the end of the season.
With Oscar arriving from Internacional, a regular spot in the team looked unlikely and he was thus sent on loan to Bundesliga side Werder Bremen where he has impressed, but he insists he will not be thinking about next season until this term draws to a close.
Speaking to Bild, the 21-year-old said: "It is not the right time to talk about my future. I think it will only happen around three match days before the end of the season, maybe even after the season."
However, the German club's sporting director Thomas Eichin had a different view on the matter and expects to have discussions with the player and his agent in the coming weeks.
Eichin said: "We want to talk in the near future and check the situation. We must get a feeling about how Kevin and his agent see the situation."
