Usain Bolt has been tabled an official contract by the Central Coast Mariners but the man who would be his coach, Mike Mulvey, says he knows nothing about it, suggesting there is no room for the Jamaican sprint star in his A-League attack.

The Mariners made the offer to Bolt's management over the weekend, with the news breaking while the Mariners were playing their season opener against Brisbane Roar on Sunday.

Sources suggest the deal is worth $150,000 – a long way short of the $3 million that had previously discussed with Bolt’s management. And while it would allow him to conceivably begin playing A-League football immediately, Mulvey’s reaction would suggest not everyone at the Mariners is on the same page when it comes to the eight-time Olympic champion.

Bolt was reportedly in Melbourne considering his options. His long-time agent Ricky Simms confirmed to Fairfax Media that Bolt had received a contract offer but did not provide any further detail.
