Six top European clubs have made Chelsea defender Antonio Rudiger a transfer target, according to a report.

The German international is out of contract at Stamford Bridge next summer, meaning teams will be able to offer him a pre-contract deal in January ahead of a free transfer.

Bayern Munich, Juventus and Real Madrid have all been linked with signing Rudiger.

According to Sky Sports News, there are six clubs ready to offer the 28-year-old a pre-contract in the new year.

The report adds that Chelsea are in talks with Rudiger over a new deal, but the defender is happy to take his time to assess his options ahead of what he believes will be the biggest contract of his career.

Rudiger has made 156 appearances for Chelsea since signing from Roma in 2017.
