Bolt 'not stressed' despite dip in form

Reigning 100m and 200m sprint champion Usain Bolt reveals he is "never stressed" despite not being in top form with just two months to go until the Olympic Games, stating "even if I lose every race leading up to the Olympics it won't even bother me".

The Jamaican world record holder admits he is not at his best, but reveals his "coach is happy with where I am at" and he has always had "one focus - to go to the Olympics and do great things".
