Usain Bolt 'retires' from football, says it was 'fun while it lasted'

Usain Bolt's dream of playing professional football is over.

The Jamaican former sprint star has ended his quest to make it in football, telling ESPN he might have done things differently if he had his time over.

"I don't want to say it wasn't dealt with properly, but I think we went about it, not the way we should and you learn your lesson, you live and you learn," he told ESPN.

"It was a good experience. I really enjoyed just being in a team and it was different from track and field and it was fun while it lasted."

Bolt had training stints with teams in Germany, South Africa, Norway and Australia, most recently with A-League outfit the Central Coast Mariners. 

He scored twice in a trial match for the Mariners against a bunch of local battlers. That led to a contract offer from Maltese team Valetta, but he did not take it up.

He said his focus now was on building his business.

 "I'm just doing many different things ... the sports life is over, so I'm now moving into different businesses, I have a lot of things in the pipeline, so as I say, I'm just dabbling in everything and trying to be a business man now."
