Freddie Haggerty is confident that his older brother has the ability to fight in the trenches when he needs to.
Jonathan Haggerty is a very skilled striker, but just because he's technically very strong doesn't mean that he hasn't got a warrior mentality. 'The General' has proven several times in the past that when the going gets tough, he doesn't crumble under the pressure.
His younger sibling believes that this could be a crucial element to one of his toughest fights to date as he faces Superlek Kiatmoo9 in the main event of ONE 168.
With the ONE bantamweight Muay Thai world championship on the line, Haggerty will know that very few can match his opponent skill-for-skill.

However, the Brit won't back down from a firefight on September 6.
In a recent interview with ONE Championship, Freddie spoke about the toughness that his brother brings to the table by referencing his fights with the likes of Rodtang and Felipe Lobo where he demonstrated this aspect of his game:
"He's been in the deep waters with these Thai guys. Even against Felipe Lobo, he's been in the deep waters, and he knows he's got that dog in him."
