Former world champion Amir Khan believes unbeaten prospect Conor Benn will have his hands full with veteran Samuel Vargas.
Benn, 24-years-old, will take a step up in class when he faces Vargas this coming Saturday night.
Khan collided with Vargas in 2018.
And while Khan was victorious, he was dropped in the fight and was seriously rocked in the late rounds.
Vargas is now 2-2 since he contest with Khan.
He lost a ten round split decision to former world champion Luis Collazo and suffered a stoppage loss at the hands of Vergil Ortiz. Only Danny Garcia, Errol Spence and Ortiz have stoppage wins over Vargas.
"[Vargas] can get in there and have a little tear up. He can throw a good shot as well. He's got decent power. I think it's a massive step-up for Conor Benn. I think Conor will have his hands full in that fight," Khan told Sky Sports.
"Since obviously after he fought me, he has been in one or two difficult fights, Samuel Vargas, and he's been beat after I beat him. But I still think he's a dangerous operator. You have to stay focused throughout the whole fight, because this is boxing, one punch can change a fight. Samuel has that power, has decent skills, which can cause any fighter problems."
Khan believes Benn is fully capable of becoming a world champion in the future.
"Yes, he can," said Khan. "As long as you believe in yourself, you work hard, you train hard.
"You always wake up every morning, knowing that one day, where your end goal is. Chase your dreams, chase your goals."
