"The Club can confirm that a contract proposal has been offered by the Central Coast Mariners and negotiations remain ongoing with Usain Bolt and his management regarding his football future," the statement said.
"Both parties are eager to explore all options and ensure that if there is a suitable way forward for both player and Club, the two parties will keep working together and formalise an agreement. The Central Coast Mariners want to ensure that Usain Bolt is given every chance possible to fulfil his dream to become a professional football player."
The A-League club admitted that it would be difficult to come to an agreement with Bolt unless commercial partners contributed to bolster the deal.
"Regarding the commercial terms of the negotiations, Usain Bolt's management and the Central Coast Mariners are in conversations with external partners to find a commercial solution that suits all parties.
"It is important to note, that contract values speculated in the media are incorrect. Without the financial contribution of an external third-party, it is unlikely that Usain Bolt and the Central Coast Mariners will agree to terms."
Bolt, who retired from track and field last year, was in Melbourne during the Mariners' opening match, with News Corp. Australia earlier saying he was considering his options after being offered a contract.
He has been training with the Mariners for several months and scored two goals in a trial match two weeks ago in his first start.
To ensure Bolt's situation doesn't become a "distraction" for his teammates as they prepare to face Melbourne City, he will not train with the main squad this week.
