WATCH: Usain Bolt's concerning A-League auditions

The sprint star failed to impress during his most recent appearances on the pitch

While there's no doubting Usain Bolt's speed, his ability on the football pitch isn't so certain with A-League side Central Coast Mariners set to offer him a trial

Since retiring from athletics, the Jamaican has trained with Borussia Dortmund and most recently linked up with Norwegian side Strømsgodset.

The 31-year-old in fact took to the pitch for the side as a 70th-minute substitute against Norway's Under 19s in early June with his highlight reel not making for the most convincing viewing.

Though on the pitch for less than half an hour, Bolt struggled with his first touch and, playing as a forward, failed to make the runs you'd expect of the sprint king.

Strømsgodset would ultimately lose the game 1-0 with Bolt departing the club after spending a week training with them.

Since that game Bolt has also played an exhibition Soccer Aid match at Old Trafford - captaining the Rest of the World team and even finding the back of the net, only for the goal to be ruled out for offside. 

Bolt's most recent football outing was another exhibition match, this time against a France 1998 side with the 31-year-old showing some signs of improvement.

Though putting a good chance just wide, he looked a bit more confident on the ball but still struggled to make the most of his blistering speed.

Bolt is expected to spend around a month with the Mariners to prove his footballing ability with a rumoured $900,000 contract potentially awaiting him should he impress.
