As he came out onto the track for the start Farah had gestured at the crowd for more noise, and he did so again as the contest began to develop.
The Brit, the undisputed force in long distance racing over the past six years, was pushed to the brink, but eventually ran a personal best time of 26:49.51 to take the gold medal in what was the fastest race over the distance this year.
Farah has stood by Salazar publicly since a BBC Panorama programme about his coach in 2015 and Black added: 'If Mo's here alone, the result would be the same. "I've got a few cuts and bruises, just recover and get ready for the 5k", he said.
"But what a way to end my career in London", he said. This was very special.
On the fifth anniversary of "Super Saturday" - when Farah, Jessica Ennis and Greg Rutherford all won gold medals in the space of 45 minutes inside the same stadium at the London 2012 Olympics - the atmosphere was once again electric in the capital.
Tanui was thrilled with his unexpected bronze medal on Friday night, but denied clipping Farah's heels during the final lap.
The 34-year-old will go for his third consecutive gold at what will be his final run-out at the tournament. "I had to get my head around it", Farah said after the win.
"It was wonderful tonight, I had to get my head around it".
Doping allegations repeatedly levelled at Olympic champion runner Mo Farah are inevitable, according to a fellow athlete who has known him for decades. "Anything is possible if you train hard". "I'm not disappointed in the race, I'm just disappointed I'm not stepping on the podium, that wasn't enough to get me on the podium". "I didn't think I'd lose but I knew it was very tough". "With two laps to go I didn't have the gas to go with them".
Other Irish athletes worth keeping an eye out for over the next week are Rio fourth place finisher Thomas Barr in the 400m hurdles, 400m sprinter Brian Gregan and Mark English in the 800m, who all won national titles at Morton Stadium recently.
He continued; "It helped a lot having that experience".
Soon, Farah had the race under his control and he was in his usual forthright position at the front as the bell rang for the final lap.
He pulled the five of them - his wife Tania and four children - from the crowd. "I've worked so hard to be here and I have to remain focused".
And it will take something special from his opponents to deny him that 11th and final track crown before he switches to the marathon where even greater riches await. With the race continuing at a fairly consistent pace throughout, it was with four laps to go that the heavy favorite moved further towards the front.
He made a decision to train in Kapchorwa on the foothills of Mt Elgon in Uganda which he said it gave him ideal conditions as he prepared for Friday's race.
