During the Roman Abramovich era, the Blues became known for signing players and allowing them to spend several different loan periods elsewhere.
On some occasions, the players in question returned to earn game time with the first-team squad, but there are countless examples of players signing and leaving Chelsea without making a senior appearance.
However, a change in FIFA regulations means that clubs are unable to loan out more than eight players to foreign clubs during any particular season.
In 2021-22, Chelsea only allowed nine players to move overseas, but some of the players who spent time at different domestic clubs are now in a stronger position to go abroad.
With that in mind, Nizaar Kinsella of the Evening Standard says that Baba Rahman, Matt Miazga and Xavier Mbuyamba have all been put up for sale.
Since signing for Chelsea in 2015, Rahman has made just 23 appearances for the West Londoners in all competitions, all of which came during his first campaign at Stamford Bridge.
The Ghana international has since spent seven loan spells elsewhere, the most recent coming at Reading with 29 starts coming in the Championship.
Miazga's stint with Chelsea has taken a similar trajectory, the United States international making just two Premier League starts since January 2016.
Instead, the centre-back has represented five different clubs, the last team to use the 27-year-old being Alaves with 11 appearances being made in La Liga during the most recent campaign.
When Chelsea manage to prise Mbuyamba away from Barcelona in August 2020, it was regarded as somewhat of a coup with the player being handed a three-year contract.
However, the Dutchman, now 20 years of age, has failed to make a single first-team outing and was allegedly denied the chance to go out on loan earlier this year with Chelsea fighting to remain in Premier League 2.
Although a loan move would have made sense for the upcoming campaign, Chelsea seemingly do not want to use one of their eight loan slots on a player who is unlikely to want to extend his contract past 2023.
