Jackson's absence from the squad is likely due to the recent signings of Liam Delap and Joao Pedro by Chelsea. Delap joined from Ipswich, while Pedro moved from Brighton.
According to reports, Enzo Maresca, Chelsea's coach for the game, made the decision to leave Jackson out of the squad. This move may be a sign that the player's time at Stamford Bridge is coming to an end.
Newcastle United and Bayern Munich are reportedly interested in signing Jackson. Newcastle were unable to secure Benjamin Sesko, which may have led them to look for other options. Bayern Munich is also keeping a close eye on the player's situation.
Other players who were left out of the squad, such as Christopher Nkunku, Ben Chilwell, Raheem Sterling, Renato Veiga, and Axel Disasi, are also looking for new clubs.
