The January transfer window is now open, with Chelsea continuing to be linked with a host of big names.

The Blues were the biggest spenders in the summer, splashing more than £200m, but they have been tipped to do yet more business in January as they look to bridge the gap to the leading pack in the Premier League.

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

Wednesday morning's Chelsea transfer talk news roundup:

Borussia Dortmund 'could be forced to lower Jadon Sancho demands'

Borussia Dortmund could reportedly be forced to lower their asking price for Manchester United target Jadon Sancho.

The former Manchester City youngster was the talk of the summer transfer window regarding a move to United, but he stayed put at the Westfalenstadion after the Red Devils failed to stump up Dortmund's £108m asking price.

Ole Gunnar Solskjaer's side are expected to reignite their interest in the England international this summer, and they are reportedly set to be joined by Chelsea and Liverpool in the race for his services.

According to Sport1, Dortmund's significant financial losses in the wake of the coronavirus pandemic could force the Bundesliga giants to demand a lower fee for Sancho.

The report claims that Dortmund know the sale of Sancho will be a huge help in their attempts to balance the books, but they realise that no club is likely to shell out a nine-figure sum in the current economic climate.

The attacker endured a slow start to the 2020-21 campaign, but he nevertheless boasts six goals and 13 assists across all competitions for Edin Terzic's side this term.

Thomas Tuchel appointment 'boosts Chelsea's Dayot Upamecano pursuit'

Chelsea could supposedly be handed a boost in their pursuit of RB Leipzig's Dayot Upamecano as Thomas Tuchel prepares to take over at Stamford Bridge.

Following the sacking of Frank Lampard on Monday morning, former Paris Saint-Germain and Borussia Dortmund manager Tuchel is expected to take the reins by the end of the week.

Upamecano - one of the most sought-after defenders in world football - will be available for a modest figure of £38m this summer due to a clause in his Leipzig contract.

According to Bild, Tuchel's appointment at Chelsea could tempt the Frenchman into moving to the English capital, as the defender has heard good things about the 47-year-old's coaching from his France teammates.

However, Bayern Munich's interest in the defender is well-documented, while Liverpool and Manchester United are supposedly ready to fight in what is sure to be an intense battle for his signature.

Upamecano has already turned out 24 times for Leipzig in all competitions this term, scoring one goal and setting up another in the Bundesliga.
