Manchester United tried to lure Jurgen Klopp away from Borussia Dortmund in 2014 by describing themselves as "an adult version of Disneyland."
The German was strongly linked with a switch to Old Trafford as the club struggled under David Moyes following Sir Alex Ferguson's retirement.
And according to the upcoming biography on Klopp - Bring the Noise, written by Raphael Honigstein - United's executive vice-chairman Ed Woodward flew to see Klopp just weeks before Moyes' sacking.
However, Klopp apparently found Woodward's bizarre comparison between United and Disneyland “a bit unsexy” and therefore decided to remain at Dortmund.
Serialised in the Daily Mail, the book reads: “Manchester United executive vice-chairman Ed Woodward had flown out to see Klopp in Germany.
“Klopp wasn't entirely convinced by that sales pitch — he found it a bit 'unsexy', he told a friend — but he didn't dismiss the proposition out of hand either.”
Klopp, 50, would later meet up with Dortmund CEO Hans-Joachim Watzke to confirm he had made up his mind and that he would be turning down United's offer.
