Floyd Mayweather has belatedly responded to Amir Khan's callout, claiming that he only sets up fights with people who deserve it.

The former welterweight champion called out Mayweather in October as he hoped to tempt "Money" to come out of retirement once again and face him in the ring.

Khan (31-4 record) has not fought since he was infamously knocked out by Canelo Alvarez in May 2016, but claimed his speed would be too much for the former five-weight world champion.

"Who knows? Floyd is a great fighter I just hav (sic) something he's not faced, speed," Khan wrote on his Twitter profile last month. "Floyd knows I'm not the 1 to back down.

"I know it's been a year I've not fough (sic) due to (a) hand surgery. I'm ready to make comeback at 30 years of age. Say what you like, Canelo was getting out-boxed. I was winning on (the) cards.

"He had power and caught me with a huge right (hand). That's boxing. Mayweather doesn't have the power... in any fight I've never been out-boxed.

"Mayweather-Khan (sic) fight would be a game of chess. Speed, movement and accuracy will cause him problems."

The 40-year-old American did not respond straightaway, however. Since then, Khan became a part of ITV's I'm A Celebrity...Get Me Out of Here! reality TV series where a recent clip of him getting freaked out by a snake notably went viral.

Mayweather used that clip to take a jab at Khan as he revealed how he is used to being called out, even in retirement.

"It's nothing new for me," Mayweather said, as quoted by Express. "Every fighter out there wants a chance against me because they know, win or lose, it's going to be a big payday for them.

"I have always maintained I am nobody's meal ticket."

Mayweather then added that the Pakistani-Brit was not deserving of a fight with him and that he should stick to television.

"I only set up fights with fighters that deserve it and who are going to be part of a great fight for fans," he said. "Only last month, I read about him [Khan] calling me out of retirement.

"He wants to fight the best pound-for-pound fighter in the world and now I hear is running away from a few snakes and spiders. Please! He needs to get real and stick with TV."
