If you are bothered enough to go through every squad in the Premier League, you're bound to find at least one ex-Chelsea player there. Whether that's a testament to Chelsea's transfer strategy or purely because they aren't deemed good enough is a story for another time. So why do we see so many Chelsea players leave?
Well, the amount of managers arriving and then walking out the exit door is getting higher, and if some players don't get on with the manager, they leave.
Player turnover at Stamford Bridge has been excessively high. Not so much anymore, but in the big spending days up until 2007, Chelsea brought in the likes of Hernan Crespo, Andriy Shevchenko and Michael Ballack, but all were out of West London within two to three years after joining.
Even now, Chelsea have the best part of 24 players out on loan, around a third of which play top-flight football for those clubs.
And while the Blues are bound to have made millions from player sales, we've picked out seven players who we think they should have thought twice about before pushing them out the door.
