Bolt, 32, scored a brace in a pre-season friendly on Friday which made global headlines but the performance has now seemingly attracted interest from Europe.
Currently, on a six-week trial period with A-League side Central Coast Mariners, the eight-time Olympic Gold medalist is said to be close to finally achieving his ambition of becoming a professional footballer.
"His transformation just since I've been here is massive. He needed a different type of fitness. He’s used to being explosive and running in straight lines. He's had to get used to stopping and checking and building his stamina.
"If he pulls it all together he can be some threat. He can bump guys off easily with his strength, he’s got aerial presence and then there’s the fear factor of his pace. Defenders won't want to allow him to turn or run behind them because they know they won’t catch him.
"The great thing is Usain’s so humble. You forget you are with a global icon. He stays behind to work after training and asks for advice yet, when he talks, it’s a bit like John Terry at Aston Villa last season, everyone in the dressing room wants to listen."
