Alberto Salazar was never in any doubt that Mo Farah would stick by him despite the doping allegations surrounding the American coach.

Salazar this week issued a lengthy rebuttal of almost 12,000 words denying the claims by BBC Panorama and US investigative website ProPublica that he violated several anti-doping rules, including using testosterone medication on Farah's training partner Galen Rupp when he was 16 in 2002.

Salazar is reportedly under investigation by the US Anti-Doping Agency with investigators questioning athletes at the Nike Oregon Project, leaving open the possibility that double Olympic champion Farah could be quizzed as well. There is no suggestion of any wrongdoing on the part of Farah.

The 32-year-old confirmed on Friday that he was sticking by Salazar and the coach does not believes there was ever a chance he would leave.

"There was never any doubt in my mind he was going to stay," he said.

Farah said in his statement: "Following all the speculation I want to make it clear where I stand. Although it's been a difficult time, I asked Alberto to respond to the allegations made against him and he has now done so in full.

"As someone I've worked with for many years, I feel I have to believe in Alberto and the evidence he has provided. Based on that evidence, I will continue to work with him and hope now that I can focus on what I do best - training hard to win medals for my country."

Farah is to return to the track on July 9, for the first time since the allegations broke.

Organisers of the Diamond League meeting in Lausanne say Farah will compete in the 5,000 metres. He is also due to run in the Diamond League meeting in Monaco on July 17.
