Bolt's two-goal performance ignited the interest of several European clubs, most particularly Malta's Valletta FC.
Bolt's agent in Australia, Tony Rallis, also confirmed the approach, ESPN said.
In the video Bolt said: "I asked the lady, 'Why am I getting drug tested when I haven't signed for a club yet?' And she said they told her I'm an elite athlete so I have to get tested".
However, the Jamaican has yet to earn a professional contract and wasn't included in the Mariners squad for their opening A-League game in Brisbane. With no contract, Bolt is not eligible for selection.
Central Coast Mariners' Usain Bolt receives instructions before being substituted on.
Some players even have their skill move and weak foot ratings changed by EA Sports, with fans of the game often petitioning the developers to make these changes following real-life developments.
HAVING provided Usain Bolt a platform to showcase his worth and invested nearly two months of toil, Central Coast risk quickly losing sight of the world's fastest man and football's most famous trialist.
Mulvey's pre-match media conference saw the Mariners boss questioned on the future of Bolt, but he was not keen to discuss his future.
However, agent Ricky Simms said his client had decided against a move to Malta, with Valletta having gone public in their pursuit of the 32-year-old.
"I'm really not interested in it [contract speculation] to tell you the truth", he said.
He described Bolt as a legend and fantastic person and praised him for bringing global attention to the Mariners and the A-League.
"We're concentrating on the season and just looking forward to round one and putting into practice what we've been doing at training for the last 12 weeks".
Bolt who retired from athletics in 2017, has trained with Borussia Dortmund, South African club Sundowns and Norway's Stromsgodset.
