Mo Farah believes that he owes his long-distance double at the World Championships to coach Alberto Salazar.
The Briton claimed gold in the 5,000m on Friday, having already secured the 10,000m title in Moscow earlier this week.
This medal haul is a replica of that he achieved at the London Olympics last year, and Farah feels that his move to America to work with Salazar three years ago is imperative to his recent success.
He said: "It was a lot more hard work than last year. Alberto has done a great job for me. He made my career, I never thought I would achieve something like this.
"I know I work hard for it, but you need the right people and I'm glad I've got the right people.
"It was very tough, I thought the guys would have worked more as a team. I've had a lot of pressure, but at the same time I enjoy it. I am very proud to represent my country and hold the Union Jack."
Farah has revealed that he plans to compete in the London Marathon in 2014, but has insisted that he will not quit running on the track to focus on road races.
