Michael Essien has been omitted from Chelsea's Champions League while all four of Jose Mourinho's new signings have made the cut.
The decision seems somewhat peculiar seeing as Essien has always been one of Chelsea manager Mourinho's favourite players.
Essien has struggled to hold down a starting spot in Chelsea's side in recent years due to a series of knee injuries.
The Ghanaian midfielder - who was one of the best midfielders in the Premier League before he started to pick up niggles - was loaned out to Mourinho's Real Madrid side last season where he made 34 appearances for the La Liga giants.
Essien is yet to feature for the west London side this season as Mourinho has decided to start Frank Lampard and Ramires in Chelsea's midfield.
Chelsea should be able to progress through their Champions League group, which includes Basel, Steaua Bucharest and Schalke, without the services of Essien - but it remains to be seen whether Essien's long-term future remains at Stamford Bridge.
Chelsea's squad is as follows:
