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.

Thursday morning's Chelsea transfer talk news roundup:

Bayern Munich 'pull out of Kai Havertz race'

Bayern Munich are reportedly prepared to end their interest in securing a deal for Bayer Leverkusen playmaker Kai Havertz.

Having contributed 12 goals and six assists in the Bundesliga this season, the 21-year-old is attracting strong interest from Chelsea.

However, Bayern have been long-term admirers of the Germany international, who is expected to move to a bigger club during the next transfer window.

According to Bild, club officials are now against paying in the region of £90m for Havertz, instead preferring to focus on other targets.

The report suggests that Bayern's stance would remain the same even if they were able to raise funds from the sale of Thiago Alcantara.

Chelsea are allegedly in the process of opening negotiations with Leverkusen for their most prized asset.

Atletico Madrid 'do not want Kepa Arrizabalaga in Jan Oblak deal'

Atletico Madrid will reportedly resist any attempt by Chelsea to include Kepa Arrizabalaga in a deal for Jan Oblak.

Since the beginning of this week, the Blues have been linked with a big-money approach for the Slovenia international, who is widely regarded as one of the best goalkeepers in world football.

However, in order to reduce their financial outlay, Chelsea are said to be keen for Arrizabalaga to move in the opposite direction.

According to the Daily Mail, that is a solution which would not work for Atletico, despite being able to generate funds for other targets at the same time.

The report suggests that Atletico are only prepared to consider bids which are in the region of Oblak's release clause, said to be £110m.

Diego Simeone has acknowledged that he would prefer to keep Oblak at Wanda Metropolitano.
