Tottenham Hotspur have reportedly made an offer for Chelsea defender Antonio Rudiger.

The Germany international is allegedly surplus to requirements at Stamford Bridge and is expected to leave Frank Lampard's side before the transfer window closes on October 5.

A number of clubs, including Paris Saint-Germain and Barcelona, have been mentioned as potential suitors for Rudiger, who has made 115 appearances for the Blues in all competitions.

However, according to Italian journalist Nicolo Schira, Spurs have now lodged an official bid for the 27-year-old as Jose Mourinho's side look to bring another centre-back to the club.

Schira claims that Tottenham are keen to loan Rudiger for the 2020-21 campaign but also want the option of signing him on a permanent deal next summer.

The German is yet to make a single appearance for Chelsea this season and has not even been on the bench for Lampard's side since their opening game of the new Premier League campaign.
