Such is the confidence of British boxer Amir Khan ahead of his upcoming fight against Saul 'Canelo' Alvarez that, earlier this week, he even backed himself to switch sports to Mixed Martial Arts and give the UFC's biggest name, Conor McGregor, a run for his money.
It hasn't taken long for his comments to draw scorn from those within the MMA community, however. Two days on from claiming he "fancied his chances" against any UFC fighter - Featherweight champion or otherwise - Khan was put in his place by former UFC Heavyweight Brendan Schaub.
Schaub, speaking on his 'Fighter and the Kid' podcast, proceeded to break down exactly why Khan was so wrong about his bold claim.

"Especially Khan being a lighter guy, he's not going to be a knock-out guy," began the retired UFC fighter. "I don't even know where to begin on this...
"He's that boxer saying, 'I don't need a ground game; I could walk into the Octagon.'...I'll tell you this right now, you could take a low-level amateur at 155 pounds - a guy who might not even make The Ultimate Fighter house - and he would mop the floor with Amir Khan. Mop the floor."
Schaub actually admitted to being a big fan of Khan in the ring but the 6-4 UFC fighter wouldn't entertain the Bolton-born boxer's chances in the octagon:
"All he (Khan's opponent) would have to do would be cover up, get inside and get an underhook. [Khan] would go for a ride."
Khan is already making something of a jump this weekend when he will move up two weight classes to fight Alvarez. The jump to UFC is, though, another thing entirely.
Backing his chances
Khan certainly didn't seem put off by the prospect when making his comments earlier this week.
"My speed would be perfect, it’s hit and move. And I can kick hard," he said, via The Daily Star.
"I’ve already done MMA training. It’s good for preparing to fight a guy like Canelo [Alvarez] who likes to put the pressure on.
"I was at the last SFL show in Dubai, watching the guys in my weight closely. Even though I have no experience of MMA, I could have stepped in and done the business."
He went on to point out that McGregor's most high-profile win - his 13-second K.O. victory over Jose Aldo at UFC 194 - was achieved through "a proper boxing move".
You certainly can't argue with Khan's confidence. However, the UFC has chewed up and spit out plenty of confident fighters in the past. In Schaub's eyes, that is exactly what would happen to the boxer if he ever did attempt to make good on his word.
