Here at Anytime football, we look at six players who could be on their way out of Stamford Bridge in the coming weeks.
The 20-year-old winger struggled to hold down a regular starting berth at Chelsea last season, and the likes of Hakim Ziyech and Christian Pulisic were preferred over him.
It will be interesting to see if the youngster can impress Thomas Tuchel during pre-season and hold down a place in his starting lineup.
Hudson-Odoi needs to play more often in order to fulfil his potential, and if Chelsea cannot offer him that platform, he needs to leave for his own development.
The 26-year-old was on loan at Aston Villa last season, and he had a disappointing spell at the West Midlands club.
Chelsea have the likes of Kai Havertz starting in his position, and Ross Barkley is unlikely to get regular game time at Stamford Bridge next year.
The 25-year-old midfielder was on loan at Fulham last season, but he struggled to hold down a regular starting berth for the Cottagers.
Ruben Loftus-Cheek will have to work hard to impress Thomas Tuchel and convince him that he deserves a chance at Chelsea next season.
The 26-year-old Frenchman is behind Antonio Rudiger, Andreas Christensen, Cesar Azpilicueta and Thiago Silva in the pecking order at Chelsea. He will have to move on to play more often.
Despite managing to score 30 goals for Chelsea in the last two seasons, Tammy Abraham has not been a critical player for Thomas Tuchel, and the struggling Timo Werner has been preferred ahead of him.
Ethan Ampadu was on loan at Sheffield United, and he managed to impress with the Blades despite their relegation to the Championship.
However, Chelsea are well stocked in the defensive department, and the youngster might need to leave in order to play more regularly.
