Usain Bolt has received an offer of a “contract proposal” from the Central Coast Mariners, the Australian club have announced.

But the Mariners also say that “without the contribution of an external third party” it was unlikely that the Jamaican and the club would agree terms.

The 32-year-old former sprinter, winner of eight Olympic gold medals, has been on trial with the A-League club and recently scored two goals in a friendly.

Bolt’s brace came earlier this month in a friendly against Macarthur South West, having joined the club in August for a training period.

“There are two main terms of discussion involved in this negotiation – football and commercial,” the Mariners added.

“Regarding the football terms of the negotiations, Usain has made great progression during his time on the Central Coast and we feel that he will improve further with more individual intensive training and competitive game time.

“We are looking at ways to do this as the club does not have the luxury to be able to do this in the Hyundai A-League.

“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.

“To ensure that there is no distraction to the Hyundai A-League squad in preparing for this weekend’s match versus Melbourne City, Usain Bolt will not attend team training this week, until and if the club and Usain Bolt can agree to terms and formalise an arrangement.”
