The summer transfer window has now begun, with rumours and speculation continuing to swirl as Chelsea eye possible reinforcements.

The Blues failed to bring in a single player during the January window, despite seeing their transfer ban cut short by FIFA, but have already been busy this summer.

Here, Sports Mole rounds up the latest news on possible comings and goings from Stamford Bridge.

Friday morning's Chelsea transfer talk news roundup:

Tottenham Hotspur 'make official bid for Antonio Rudiger'

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.

Chelsea 'set for deadline-day clearout'

Chelsea are reportedly looking to ship out three more players before the transfer window closes next Monday.

The Blues have been heavily active in the market and have welcomed a host of big-name signings to Stamford Bridge over the summer, including Timo Werner, Hakim Ziyech, Kai Havertz, Ben Chilwell, Thiago Silva and Edouard Mendy.

With Frank Lampard seemingly now focused on offloading players before the deadline, the Daily Star reports that a trio of players at Stamford Bridge could be heading for the exit door within the next few days.

Marcos Alonso's future has been shrouded in uncertainty since Chilwell arrived in the capital, and the report claims that the Spaniard is almost certain to depart.

Fellow defender Antonio Rudiger has found himself out of Lampard's squad recently and questions have naturally been raised over his future, with the Germany international being linked with Tottenham Hotspur and West Ham United.

Finally, Lampard has admitted that midfielder Ruben Loftus-Cheek may be allowed to leave on loan in order to get more playing time.
