The buildup to the summer transfer window has very much begun, with rumours and speculation continuing to gather pace as Chelsea look to boost their squad ahead of the 2020-21 campaign.

The Blues did not sign any new players in January despite having their transfer ban lifted, but they have already secured deals for Hakim Ziyech and Timo Werner, with more expected to follow.

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

Saturday morning's Chelsea transfer talk news roundup:

Report: Chelsea close to sealing deal for Bayer Leverkusen star Kai Havertz

Chelsea are reportedly edging closer to securing the signing of in-demand Bayer Leverkusen attacker Kai Havertz.

The Blues have been strongly linked with the Germany international over the last few weeks, with the London giants thought to lead the race despite interest from Manchester United and Real Madrid.

An agreement is believed to be in place between Havertz and Chelsea, but the Premier League side still have to finalise terms with Leverkusen.

Football.London claims that talks are progressing well and the 21-year-old, who is valued at £81.5m, is close to becoming Chelsea's latest high-profile signing.

Chelsea to move for Matthias Ginter?

Chelsea are reportedly weighing up a move for Borussia Monchengladbach centre-back Matthias Ginter.

The Germany international played a leading role for Monchengladbach during the 2019-20 campaign, making 31 top-flight appearances for the Bundesliga outfit.

Kicker reports that Frank Lampard has set his sights on Ginter, who would boost a defence that has struggled to produce clean sheets on a consistent basis during the current season.

However, even though Ginter's contract with Monchengladbach has just under a year left to run, the report claims that the Bundesliga outfit will still demand a hefty fee for the 26-year-old.

Manchester City to rival Chelsea for Atletico Madrid defender Jose Gimenez?

Chelsea will reportedly face competition from Manchester City if they wish to sign Atletico Madrid centre-back Jose Gimenez during this summer's transfer window.

The Blues are expected to move for at least one new central defender ahead of the 2019-20 campaign, and Gimenez has allegedly been identified by Frank Lampard's side as a possible recruit.

However, according to ESPN, Man City are also in the running for the Uruguay international, who still has three years left to run on his contract at the Wanda Metropolitano.

Atletico are thought to be unwilling to sell the 25-year-old for anything under his £110m release clause, though, which could ultimately price him out of a summer switch to the Premier League.
