The agent of Stuttgart defender Antonio Rudiger has admitted that Chelsea and Wolfsburg have both expressed an interest in signing the player.
The 22-year-old came through the club's youth system, and currently has a contract with Stuttgart through until 2017.
Sahr Senesie told German magazine Kicker: "I know of interest from Wolfsburg and Chelsea. Antonio would prefer to stay in Germany."
Injuries limited Rudiger to just 19 games for Stuttgart last season.
