Recently Chelsea have been facing issues in renewing the contracts of many star players, such as Andreas Christensen, captain Cesar Azpilicueta, star defender Antonio Rudiger and the ever-present Thiago Silva.
The 25-year-old has had a successful career at Stamford Bridge ever since graduating from the academy in 2013.
The Danish defender had a successful loan spell at Borussia Monchengladbach in the Bundesliga from 2015 to 2017, and since the appointment of Thomas Tuchel as Chelsea manager in early 2021 he has turned out to be one of the Premier League's best defenders.
The negotiations for a new contract had already started in the early days of the 2021/22 season, but since then, talks have fallen through with the player's manager demanding a three-year contract instead of a five-year contract that Chelsea had reportedly offered.
He wants to stay at the Bridge and is hoping to settle talks with the club in the coming days.
The German arrived at Stamford Bridge from AS Roma in 2017 for £29 million on a five-year contract, which expires in six months.
The 28-year-old enjoys playing under Tuchel as he has shown with his mouth-watering performances recently.
He is 'hoping' to renew his contract with Chelsea, and the club also want him to stay, but Rudiger is not happy with his current wages and wants a raise, while the offer made by Chelsea is not sufficient to convince him to stay at the club.
Chelsea and Rudiger are both working to find a middle-ground.
The 32-year-old arrived at the Bridge from Olympique de Marseille in 2012 for the minor fee of £7 million, and since then, Chelsea fans have nicknamed him 'Dave'.
The Spaniard has made over 400 appearances for Chelsea and is their captain, but since his contract ends in six months, big teams like Barcelona have shown an interest in signing him on a free transfer.
However, Chelsea are 'highly likely' to renew the contract in the coming months.
The 37-year-old arrived at Chelsea last season on a free transfer from Paris Saint-Germain on a one-year deal, but this was then renewed for another year.
His contract expires in the summer, and Chelsea have hinted at giving him another year at the Bridge.
Will Chelsea manage to get all of these players signed on contract extensions?
