PSG haven't stopped their pursuit of Europe's best free agents.

The Ligue 1 giants completed free transfers for Lionel Messi, Gianluigi Donnarumma, Georginio Wijnaldum and Sergio Ramos this summer.

Now sporting director Leonardo is turning his attention towards Chelsea defender Antonio Rudiger, per Le10 Sport.

Chelsea have been trying to tie down Rudiger to a new contract for some time.

But the German continues to hold out on the Blues, despite becoming an integral part of Thomas Tuchel's side.

Reports have stated that Rudiger's representatives have "barely touched base" with Chelsea chief Marina Granovskaia over a new deal.

As Rudiger's contract slowly ticks down to its expiration date in June 2022, PSG are biding their time.

The Parisians will be able to discuss a pre-contract agreement in January.

Real Madrid and Bayern Munich have also expressed an interest in signing the 28-year-old.
