Callum Hudson-Odoi
The winger is currently on loan at Bayer Leverkusen, where he has put in a number of underwhelming performances.
Hudson-Odoi has scored just one goal and contributed only one assist in 20 appearances for the Bundesliga side. Those are not the sort of numbers that will convince Chelsea to renew his contract.
A sale at the end of the season is looking increasingly likely for the 22-year-old, who was once hailed as a generational talent.
