The buildup to 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.

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

Friday morning's Chelsea transfer talk news roundup:

Antonio Rudiger 'facing uncertain future at Chelsea'

Antonio Rudiger's future at Chelsea is reportedly in doubt, with the Premier League giants yet to offer the central defender a new deal.

The 27-year-old has made 111 appearances for the Blues since arriving from Roma in 2017, including 24 outings in all competitions during the 2019-20 campaign.

The Germany international's current deal at Stamford Bridge is due to expire next summer, though, and according to the Daily Mail, there has not yet been any talks over a possible extension.

The report claims that Frank Lampard's desire to improve his defence ahead of next season could lead to Rudiger being moved on in the upcoming transfer window.

The centre-back lost his spot in the Chelsea XI after the 3-2 loss at West Ham United earlier this month but was back in the starting side against Norwich City on Tuesday night.

The Blues are next in action against Manchester United in the semi-finals of the FA Cup on Sunday.

Kai Havertz 'chooses Chelsea over Real Madrid, Manchester United'

Bayer Leverkusen attacker Kai Havertz is reportedly ready to snub both Real Madrid and Manchester United to join Chelsea during this summer's transfer window.

The speculation surrounding the Germany international continues to gather pace as he is widely expected to leave BayArena ahead of the 2020-21 campaign.

A number of clubs, including Madrid and United, have been linked with the playmaker, but according to Kicker, the 21-year-old has informed Leverkusen that he wants to join Chelsea.

Havertz enjoyed an excellent 2019-20 campaign for his German club, scoring 17 times and registering nine assists in 43 appearances in all competitions.

Chelsea are allegedly preparing to make a £62m offer for the German, although Leverkusen are in a relatively strong position to negotiate as the attacker still has two years left to run on his contract.

The Blues have already boosted their attack ahead of next season by completing deals for Morocco international Hakim Ziyech and Germany striker Timo Werner.
