Hundreds of faces from the footballing world gathered at Chelmsford Cathedral. Players, both past and present, paid tribute to a man who had meant so much.
Justin Edinburgh was 49 when he died from a cardiac arrest.
The former Northampton Town manager and Tottenham player died just weeks after guiding Leyton Orient to promotion back to the Football League
Nigel Travis, Chairman of Leyton Orient, said: “I think it's really him as a family man, I mean he and Kerri have been together I think since 13, so I think I reflect on the loss that they feel more than the loss for our football club.
"At the end of the day he's a family man, he's a father, and I think that's what is very important in life and he typified how important family was."
Spurs legend Glenn Hoddle, who himself had a cardiac arrest last October, gave his condolences to Justin's son Charlie.
Also in attendance were Spurs team mates Sol Campbell, Les Ferdinand and Chris Hughton.
Spurs and Man Utd legend Teddy Sheringham was there too. The ex-Stevenage manager played alongside Justin during the 90s.
Former MK Dons managers Martin Allen and Karl Robinson turned out alongside Peterborough United's Barry Fry.
Representatives from Northampton Town also paid their respects.
Darren Moore, Manager of Doncaster Rovers, said: "What I'd like to say about Justin, he was a former team mate of mine from Portsmouth and was a wonderful man, a family man, energetic in every way.
"Whenever you were in his presence he'd always make you feel worthy of yourself, he put you before himself, he was never hurried.
"The mere tribute in the turnout today epitomises the man he was, very passionate, a family man and very committed to his work and others around him."
Jobi McAnuff, Leyton Orient’s captain, said: "The family made a point of making it upbeat and very much celebratory and the tone of it was perfect really.
"It’s still difficult to grasp what happened, I thought everyone reflected so well on his life and spoke so positively that was the tone of the day really.”
The charity The Justin Edinburgh 3 Foundation aims to get defibrillators in all health and fitness clubs and to fund CPR classes so that many lives can be saved in his name.
It’s hoped it will be a positive and lasting legacy for a man who was so well respected and whose love of life inspired all of those who met him
