Chelsea are at a stage in their project under Todd Boehly and Clearlake Capital where they need to place a large emphasis on balancing the books with regards to the relevant financial rules.
Given the deficits that need to be made up, the Blues co-owners are hoping they are able to register a number of sales that will break into the club's top-10 outgoings of all time.
Here, Sports Mole takes you through the players that currently make the list, at least for the time being.
