Bayer Leverkusen director Simon Rolfes says that the club has not received an offer for Kai Havertz amid widespread reports that Chelsea are chasing the German star.
The Blues have been heavily linked with the German midfielder in recent weeks, having already completed deals for his compatriot Timo Werner as well as ex-Ajax star Hakim Ziyech.
Havertz's performances this season helped capture the attention of Frank Lampard's side, with the 21-year-old providing 12 goals in 30 games to guide Bayer to fifth place in the Bundesliga.
