Chelsea had a very busy summer transfer window, bringing in six senior stars in the form of Hakim Ziyech, Timo Werner, Ben Chilwell, Thiago Silva, Kai Havertz and Edouard Mendy.
However, they have had a much quieter January window so far, with no major incomings or outgoings.
Frank Lampard's side currently sit seventh in the Premier League table and they could be tempted to spend more cash in a bid to climb up the table.
Several fringe players could also leave the club in a bid to secure more regular first-team football.
Here are the latest rumours from Stamford Bridge.
West Ham United boss David Moyes has revealed that the club have not had an official offer from either Chelsea or Manchester United for Declan Rice.
Speaking to Amazon Prime, Moyes said: "They're not true [rumours of a bid], we've had no contact from either of those clubs regarding Declan and we wouldn't want any anyway.
"He's doing great for us, he's a big leader now, he's taken a lot of the weight off Mark Noble.
"He's turning out to be a really good player but also a really good boy and good around the club."

Salzburg striker explains decision to reject Chelsea
RB Salzburg's Karim Adeyemi had the chance to join Chelsea back in 2018 after he was invited to their Cobham training ground ahead of a potential move but the forward opted to join Salzburg instead.
The teenager is highly-rated by the Austrian side and believes he made the right move by joining them instead of Chelsea.
"First of all, it is important to me that I play regularly," he told Sport 1. " My focus is currently on the Austrian league. I am very happy that I have so much time here. I am fully focused on the task in Salzburg.
"I don’t know how the clubs work; after all, I don’t know the people responsible. But I would choose the club where I feel most comfortable.
"It’s not that difficult to stay on the ground. I haven’t achieved anything yet, even though I’m now playing in the first division in Austria. But I find it – in quotation marks – quite normal that I do not answer.
"My parents and family support me a lot in this. My old Unterhaching club taught me that too. But even at Salzburg we players are kept on the ground. There is also no reason why I should rise above other people. All people are equal."
