Usain Bolt has officially given up on his dream to become a professional footballer.The sprint-king had numerous trials with professional clubs, including Borussia Dortmund and Central Coast Mariners.He was even offered a contract by the Australian club but the two parties could not agree on a deal.And, three months after that contract offer from Central Coast, Bolt has announced his retirement from the sport.He admitted on Tuesday that the experience was 'fun while it lasted.'"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 Reuters, per Sky Sports."It was a good experience. I really enjoyed just being in a team and it was must different from track and field and it was fun while it lasted."Gary Lineker saw the news and he could not resist making a joke about Bolt.The Jamaican star featured in two professional games for Central Coast Mariners.In the second game against Macarthur South West United, Bolt scored twice as his side cruised to a 4-0 win.That gives Bolt a ratio of one goal-per-game, and Lineker just had to note that is a ratio that not even Cristiano Ronaldo and Lionel Messi can match.He wrote: "After his rather abrupt retirement from professional football @usainbolt has the best goal per game ratio of pretty much any player ever. 2 games - 2 goals."Not even Messi and Ronaldo can compete with that. 🐐"

Lineker even ended the tweet with a goal emoji, joking that Bolt is now the greatest player to ever play the sport.

Never change, Gary.

Bolt admitted that he was going to venture into a career in business following the end of his sporting career.

"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."
