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:

Chelsea 'finalise club-record Kai Havertz agreement'

Chelsea have reportedly finalised an agreement with Bayer Leverkusen for the club-record signing of Kai Havertz.

The two clubs are understood to have come to terms on a package which will see the 21-year-old move to Stamford Bridge for an initial €80m (£71.3m) plus €20m (£17.8m) in add-ons.

The overall fee is therefore €100m (£89.1m), which is significantly higher than Chelsea's previous record signing - the £72m they paid to sign Kepa Arrizabalaga two years ago.

However, Sky Germany claims that Havertz is yet to undergo his medical with the Blues, contrary to reports earlier this week.

The playmaker is currently on international duty with Germany ahead of their Nations League matches against Spain and Switzerland, along with Chelsea duo Antonio Rudiger and Timo Werner.

Havertz is now expected to become Chelsea's seventh signing of the summer, after Werner, Hakim Ziyech, Ben Chilwell, Thiago Silva, Malang Sarr and Xavier Mbuyamba, and will take their spending beyond the £200m mark.

Chelsea offer Bayer Leverkusen Malang Sarr in Kai Havertz deal?

Chelsea have reportedly offered Bayer Leverkusen the chance to take new signing Malang Sarr on loan as part of the deal to bring Kai Havertz in the opposite direction.

The Blues are understood to have agreed a club-record £89.1m deal for Havertz, who is expected to become their seventh summer signing in the coming days.

Sarr is one of those to have already joined Chelsea during the current transfer window, but the club have confirmed that he will be sent out on loan for the 2020-21 campaign.

Sky Germany claims that the 21-year-old has now been offered to Leverkusen as part of the Havertz transfer.

Sarr, who plays as a centre-back, moved to Stamford Bridge on a free transfer after leaving Nice at the end of his contract earlier this summer.

Chelsea have also brought in Hakim Ziyech, Timo Werner, Ben Chilwell, Thiago Silva and Xavier Mbuyamba so far, with the Havertz deal set to take their spending past the £200m mark.
