One look at the nicknames should tell them all they need to know.
Their new boss Felix Magath is an ultra-disciplinarian and fitness fanatic who has been dubbed the 'Torturer' and 'Saddam' due to the brutality of his training regimes, which have reduced players to tears.
The 60-year-old could make Sir Alex Ferguson look soft.
Any player not prepared to live up to that old sporting cliche of giving 110 per cent would be advised to give the Cottagers' Motspur Park training ground a wide berth.
Magath has managed at the very top of the game in Germany, winning back-to-back league and cup doubles with Bayern Munich and the title with Wolfsburg.
The former West Germany international has managed eight current Bundesliga clubs, with this his first job outside his homeland.
But his dictatorial style has made him a divisive figure.
Germany's Bild newspaper revealed the incredible fine system he operated in his second spell at Wolfsburg, which reportedly ranged from 100 euros for every minute a player was late for training to 1,000 euros for an unnecessary backpass.
He has ordered dawn cross-country runs, held multiple training sessions daily and is even said to have assigned his players essays on their ambitions.
One run up a Swiss mountain while in charge of Wolfsburg reportedly ended with players in tears and striker Grafite collapsing and being carried down on a stretcher
In another tale Magath is alleged to have asked Hasan Salihamidzic to perform single-arm press-ups when he has suffered a fractured arm.
His two year-spell at Schalke ended amid player unrest, with striker Jefferson Farfan quoted as saying: "Magath's military methods are ugly. Their humanity is questionable."
Fulham's players have been warned.
