I think Chelsea should spend more money to hire players to replace the players they lost this season.
Many faums players they had who got high amount of salaries there, joined the Arabian teams and that's mostly because of the more money they could get in the Saudi teams.
Chelsea wanted to rebuild the teams they had to sell some players but finding players in this situation for Chelsea can't be easy because they don't have a stable situation at all.
Chelsea is now trying to raise money as much as possible by selling its players. Chelsea gonna use it to buy the new player from another club. The fact that if many players agreed to join in chelsea like jackson, nkuku or probably moises caicedo soon.
It's just the matter of time until caicedo will be officially bought by chelsea as a new player for next season. Chelsea was not only focusing to recruit experienced player but it's also recruiting young talented player which was under 21.
Chelsea is having a lot of money to be spend very soon. It's caused by the club needs to strngthen its position in EPL again.
