Chelsea has approached several teams in the Premier League to sell Jackson. These teams include Newcastle, Aston Villa, Manchester United, and Arsenal.
The club wants to sell Jackson to raise funds and make room in their budget for new players. Manager Enzo Maresca needs to add more players to the team before the transfer window closes.
Maresca is particularly looking for a new centre-half after one of their players, Levi Colwill, suffered a knee injury last week.
