Former long-distance runner Brendan Foster believes that Mo Farah is the best British sportsman ever.
Farah won both the 5000 and 10000m gold medals at the World Athletics Championships this week to become the most decorated British athlete in history.
"Mo is the greatest sportsman that Britain has ever had," Foster told BBC Sport.
"He's Great Britain's most prolific winner of global golds and he's put former British athletes like Sebastian Coe and Daley Thompson behind him."
"Former rower Sir Steve Redgrave [who won five Olympic golds] was part of a team. Mo is on his own and it's lonely out there. He's ruthless and we've not seen that. We should be enjoying the moment. We'll never see his like again."
Farah is the first person in the world to win a "triple-double" after winning the 5000 and 10000m finals at the London 2012 Olympics and the 2013 World Athletics Championships.
