To clear up some questions on whether or not Darren Till was a nak muay, as most of this thread so far is misinformation.
Darren Till trained at Masda Liverpool from a young age prior to leaving for Brazil.
Here is him in a kickboxing match:
and him giving a lesson in Muay Thai:
He is a Muay Thai stylist. The wide more karate like stance we see from him in MMA is an adaptation he's made specifically for MMA. In fact, it's not even an adaptation that he's had until his UFC days:
There is also a distinct difference between someone with a karate style, like Kyoji Horiguchi and Lyoto Machida - and someone with a wide stance like McGregor or Till. The comparisons with McGregor are fair, as he is also not a karate fighter, he's a boxer with a snap kick.
He's got that "golden age" style thai kick that comes almost straight up, then rips a nice curve to connect.
I should also point out that the 'golden age' thai kick, is just how you are taught to kick in the UK. I've spoken to Sylvie before about my surprise at it being some sort of discovery online when that over here, is just a correct kick.
He isn't a karateka, he's an English-style Thai boxer who's adapted to a more side on stance for MMA. That doesn't erase his history with muay thai.
