As well as buying players, Premier League clubs also need to move on some members of their squad during the transfer window.
And for Chelsea that is proving ot be a problem, with the club struggling to find buyers for some of those deemed surplus to requirements.
Thomas Tuchel is reported to be keen to dispense with the services of the likes of Timo Werner, Kepa Arrizabalaga, and a number of fringe players, but finding willing buyers is proving to be a challenge.
The major issue is that clubs in other leagues cannot match the salaries that players receive at a Premier League club like Chelsea, and, where a player still has several years on their contract left, there is no incentive for them to take what amounts to a pay cut by moving elsewhere.
And now there is a risk that the Stamford Bridge side could start the season with a bunch of layers they do not want, content to sit in the side-lines and collect their wages every week.
