T hey've been to heaven but now they are at the gates of hell.
Players with incredible CVs, huge reputations and even bigger wage packets are currently going through tough spells.
Roberto Firmino
The Brazilian has emerged as the weak point of Liverpool's attacking trident which took England and Europe by storm in recent years.
His market value has dropped 20 percent in just one year and his performances are being questioned by club legends such as Jamie Carragher.
Pierre-Emerick Aubameyang
The Arsenal forward has swiftly gone from the most dangerous striker in the Premier League to having a crisis and a goal drought.
He has only scored in four matches and his confidence is close to rock bottom, with his massive contract leading some to suggest Arsenal should look to sell him.
Eden Hazard
He arrived at Real Madrid with big expectations but a near-constant succession of injuries have prevented him from even beginning to fulfill them.
Few players in the world have seen their value drop like the Belgian's in the last couple of years.
Kepa
He joined Chelsea as the most expensive keeper in history, but he has lost his place in the team and his confidence after failing to show his Athletic Club form.
He joins Hazard in having a market value that has plummeted since being a big-money signing.
Dele Alli
With Harry Kane he had been part of one of the deadliest duos in England, but he hasn't matched his teammate's progress and has falled out of favour with Jose Mourinho.
Pjanic
The midfielder arrived at the Camp Nou with a great track record but he has failed to make much of an impact for Ronald Koeman's side, being very much a back-up option for the coach.
Mesut Ozil
Once one of the brightest stars in European football, Ozil never adapted to life at Arsenal and failed to justify his exorbitant wage.
He now has a chance to turn things around for himself at Fenerbahce.
Gareth Bale
The Welshman's return to Tottenham seemed like a match made in heaven, one where he could be happy again and rediscover his past form, but it hasn't gone according to plan and Bale has once again often found himself watching on from the sidelines.
Daniel Sturridge
The former England international counts Liverpool, Chelsea and Manchester City amongst his former clubs, but at just 31-years-old he has been without a club for eight months after serving a suspension for betting offences.
If injuries allow it, Sturridge could still have a lot to give and it will be interesting to see what his next move is and he will no doubt be keen to put this rocky spell behind him.
