The Bulgarian midfielder told the club's official website: "Maybe I would like to stay next year. It would depend on whether they want me. You don't earn a contract over seven or eight games.
"I can't say anything wrong about Leeds. Everyone knows what Leeds means, and it is a massive club. Maybe there is a good chance to stay here, but I don't want to think about the future. The next three games are massive for us, and we have to get enough points to stay in this division."
