Yafai, 29, has emerged as one of the hottest prospects in the UK after turning professional earlier this year having won Olympic gold in Tokyo.
The amateur standout came through the English Institute of Sport in Sheffield and signed a long-term deal with Eddie Hearn‘s Matchroom Boxing to fight exclusively on DAZN.
He’s won both of his professional bouts to date, with knockout wins over flyweight pair Carlos Vado Bautista and Miguel Cartagena.
Or as Clarke puts it, he’s simply been ‘blowing away the competition’.
“I’m going to say it and when you put this interview out you can put this in capital letters if you want,” Clarke told GiveMeSport.com in an exclusive interview.
“I think he is the most exciting fighter to come on the scene since Manny Pacquiao.
“A little southpaw, obviously he isn’t going to go up through the weights like Pacquiao did, but I think he’s that exciting.
“That’s a big comparison there but look at Galal’s performances. He is a whirlwind mate and he is the best out of the lot. He’s blowing away the competition.
“Out of all of the Olympians we’ve had in this country, I’m telling you Galal is the best, and will be the best.
“He’s one of my best friends in the whole world and I couldn’t be more happy for him. His success is my success and I’m so happy for him. I honestly mean that.”
Big Fraze got his career off to the best possible start after bulldozing his way through short-notice replacement Jake Darnell.
Clarke, who won a bronze medal in the super-heavyweight division at the 2020 Olympics as an amateur, got the job done in ruthless fashion.
And while he has his own career to focus on, that won’t stop him from looking out for his friends and former colleagues.
He added: “Obviously once you come into the pro game, the team aspect kind of goes out the window, you’re in it for yourself really.
“But I support my friends, you know, and that’s what they are, my friends and former teammates.
“For me personally they’re friends for life. It doesn’t mean that I’m in contact with all of them every day but I still want everyone to succeed and do their best.”
