Usain Bolt has vowed to silence his critics after training for A-League outfit Central Coast Mariners for the first time on Tuesday.

The eight-time Olympic gold medallist is on trial at the Mariners and is bidding to earn a professional contract at the club.

Having previously trialed at Borussia Dortmund, Mamelodi Sundowns and Stromsgodset, the Jamaican sprint legend attended his first training session with the Australian club in hope of finally making his dream of transitioning into football a reality.

Bolt took part in a warm-up before undergoing a short passing drill and the 32-year-old, who retired from athletics last year, was pleased with his involvement afterwards.

In terms of his ability on the pitch, Bolt believes his experience of top-level sport will allow him to stay calm in front of goal.

Most importantly for Bolt, however, who holds the 100-metre world record at 9.58seconds, is that he wants to be viewed as a footballer – not the world’s fastest man.

Mariners boss Mike Mulvey suggested Bolt might even be ready to make his debut for the club a week Friday when they take on a Central Coast select XI.
