The Slovakia international is currently on a season-long loan with Dutch side FC Twente, but is contracted to the Blues until the summer of 2011.
The 20-year-old is regarded by Chelsea as an exciting prospect for the future and his representative, Milan Lednicky claims they would like to extend his current contract with the club.
"It should be a long-term contract," Lednicky told the player's official website.
"However, it is of no importance to reveal more at the moment. The situation will be clearer some time during the spring."
