Bilic, who is more wolf than man, is a master of mind-games and famously tied the hapless Steve McClaren in knots before the two sides met in a Euro 2008 qualification decider to the extent where the England boss turned up to Wembley with a Croatia shirt on.
While the inscrutable Fabio Capello may be a tougher nut to crack, the Italian's Lego-man face surely betrayed some confusion as Bilic murmured apparently contradictory epithets and chewed on a grasshopper.
"England have lost some of their Englishness," the rabid tactician claimed. "This is not an insult but a compliment."
Bilic's comments have thrown the FA into panic as they try and work out whether or not the England side 'have a point to prove' and if they should come out 'like a raging bull' against the Croats.
An emergency meeting of the nation's leading psychologists called late last night hasn't yet produced a definite ruling on what Bilic said and this morning's training session was cancelled after Frank Lampard's attempts to solve the riddle resulted in the Chelsea midfielder lapsing into a trance-like state and losing bowel function.
