According to the Bundesliga outfit, Chelsea have held talks with Bayer Leverkusen over the possible transfer of Andre Schurrle. The 22-year-old has scored 11 goals for the Leverkusen this season and was linked with a move to the Premier League club last summer.
"Rudi Voller and Michael Reschke [club officials] talked to Chelsea yesterday," a spokesman told BBC Sport.
"No decisions have been made. We are talking, nothing more."
