Athletics has been blighted by doping scandals in recent months after athletes, including the former 100m world record holder Asafa Powell, tested positive for banned substances.
The multiple Olympic champion says he makes sure he works with people he trusts as ITV News' Paul Davies reports:
The world's fastest man and Manchester United fan Usain Bolt has told ITV News that he is sure David Moyes "heard" his recent Instagram video message in which the sprinter said the Old Trafford boss needed to invest in his midfield.
"I was sitting at home and watching the game (against Liverpool) and I saw that in the midfield is where we are most weakest so I was just voicing my concern.
"I think David Moyes heard, I'm sure, because it was all over the news. I think he surely got that message. He got (Marouane) Fellaini (in) and (Shinji) Kagawa is now playing so the team is much better and a lot more stable."
Six-time Olympic champion Usain Bolt is reconsidering his retirement after the Rio 2016 Olympic Games and says he is likely to compete for a further year after that.
In an interview with Channel 5 News at his autobiography book launch at London's Selfridges store, he said: "I am definitely reconsidering. I think my fans especially have really voiced their concern about me retiring.
"They think I should carry on and so do my sponsors. I have discussed it with my coach and he says it is possible. We will see what happens but it's on the cards that I will extend it by one more year."
Hundreds of fans have queued in London to catch a glimpse of the world's fastest man, Usain Bolt, as he signs copies of his new book 'Faster Than Lightning' in Selfridges.
At the launch of his new autobiography 'Faster Than Lightning' in London, the world's fastest man said: "If you want to be the best, or you want to strive for more, you've got to set goals in life."
Usain Bolt says he plans to retire after the 2016 Rio de Janeiro Olympics.
But the sprinter told a news conference he wants to win another gold before retiring for good.
He revealed: "If I want to be among the greats of (Muhammad) Ali and Pele and all these guys I have to continue dominating until I retire.
"If I'm in great shape and I go there and do what I have to do, I think it would be a good time to retire on top and having dominated for so long."
"I'm Usain Bolt," begins the message. "I'm a big fan of Manchester United. Dave Moyes, we need a creative midfielder. One that can pass and create opportunities. Right now.
"More control," concludes Bolt. "Serious face."

Jamaican sprint champion Usain Bolt has likened himself to Tottenham's want-away midfielder Gareth Bale, by saying they are both 'speed footballers'.
Bolt said: "If you're a good passer, it's much better. Speed also helps. If you can take [Gareth] Bale for instance, he's pretty good at speed football. So I've seen this and I've said you know what I could be a pretty good footballer.
"I've played football with my friends, I've played enough charity matches in Jamaica and I've done pretty well. So I think personally, there is a possibility I could play so at the end of my track career, I'd like to try and see if it could happen."
Bolt made the comments after meeting Fifa President Sepp Blatter who, knowing the athletics star is a huge football fan, invited him to visit Fifa while he was taking part in the Weltklasse Zürich 2013 athletics meeting.
