Voller holds Schurrle talks with Blues
Reports in Germany claim that 22-year-old forward Schurrle has already agreed his part of a deal which could be worth in excess of £20million.
Voller travelled to England with general manager Michael Reschke to meet with Chelsea and talk terms over the highly-rated forward.
Asked about a deal with Chelsea, Voller told Bild: "Yes, I was in London and I have had discussions. There is nothing more to say, there is nothing decided yet."
It is also claimed in the German media that Voller asked Chelsea about the possibility of taking Belgian winger Kevin De Bruyne as part of the deal.
The 21-year-old is currently impressing for Werder Bremen on loan and Bayer are hopeful that they can take De Bruyne on loan for next season.
