Jamaica sprint star Usain Bolt will make his first appearance for A-League club the Central Coast Mariners in a pre-season match against a Central Coast amateur selection on Friday.
The eight-time Olympic champion is on trial with the Mariners, hoping to win a professional contract to play in the A-League in the season beginning in October.
'There definitely will be nerves, it's not like it's a charity game anymore,' Bolt said. 'I expect to make mistakes but I also expect to go out there, make myself proud and to push myself.
'I know I'm not going to have a perfect game.'
'I think the thing he's struggling with more than anything else right now is getting used to the football fitness,' Mariners coach Mike Mulvey said. He said in terms of skills Bolt is 'doing OK.'
