Usain Bolt has had his fair share of critics since attempting to make the switch from Athletics to football.
The 32-year-old had been on trial at Central Coast Mariners but, despite being offered a contract, Bolt rejected the offer and is currently in search of a new club.
During his time in Australia, Bolt was harshly criticised by former Republic of Ireland international and Perth Glory forward, Andy Keogh.
He described Bolt as having a 'touch like a trampoline' before commenting that he will never make it as a footballer.
"He's not going to be able to make it," Keogh told Off the Ball last month, per BBC Sport.
"It's nice to have the attention on the A-League but him playing here, that's not for me.
"He's shown a bit of potential but it's a little bit of a kick in the teeth to the professionals that are in the league."
"If there's someone who genuinely thinks he'd be a good football addition, I don't think they should be in a position to make those calls."
It's fair to say Keogh doesn't rate Bolt's chances of being a professional footballer too highly.
Bolt had previously not reacted to those comments, but he's now hit back at Keogh and he's done so perfectly.
"People are going to say what they want, I'm used to this," he told Sky Sports. "I used to do track and field, people used to think badly of me when I started and I proved them wrong every year.
"Football is something that I want. I'm sure he [Keogh] is not at the level he was when he started, you know what I mean?
"I don't take it personally, I just laugh at these things because I've met Patrick Vieira, I've met so many big football players.
"I've talked to [Paul] Pogba and [Raheem] Sterling and they are happy to see me trying, they say 'come on, you can do it'."
Bolt went on to destroy Keogh by saying he doesn't worry about comments from 'simple players'.
"They support me, so I'm not going to worry about some simple players saying some things about me because I have high-level players knowing this is a dream and what I want to do.
"This is not about all about the money. This is a dream, and I want to try and see how good I can be."
