Kell Brook believes it would be unsafe for Amir Khan to fight him following his British rival's devastating knockout loss to Saul 'Canelo' Alvarez at the weekend.
Khan's hopes of capturing the WBC middleweight crown ended in dramatic fashion in Las Vegas when he suffered the third knockout defeat of his professional career.
The Bolton fighter intimated immediately afterwards he would move back down to welterweight, where a much-awaited showdown with Brook, the IBF champion, could take place.
Brook has courted a bout with Khan for some time and took to Twitter to reaffirm his desire to make the encounter happen immediately after his compatriot's latest setback.
However, the unbeaten Brook thinks he possesses similar power to Alvarez and that a clash with Khan would produce the same outcome as Saturday.
"After the defeat this weekend, it won't be safe for him to fight me. He's had some bad knockouts," Brook told Sky Sports News HQ.
"He got knocked out in a really bad way. I punch just as hard as Canelo. It would just be a matter of time before the same thing happened.
"I respect Amir for moving up in weight and fighting him. In their mind I think they were going down the line of it was a win-win; he was up against it, against a heavier guy, so it didn't harm anything.
"If he went the distance and lost on points, it would have been good. But losing in the way he did, with a devastating knockout, was nothing good for him. He's had a few now and it's going to take it out of anyone."
Instead, Brook is focusing on a unification showdown with either WBC champion Danny Garcia or WBO belt holder Jessie Vargas.
"All I'm interested in myself (is) fighting the very best fighters out there," he added.
"I'm looking at Danny Garcia, Jessie Vargas. I want an exciting fight. That's what we're looking at."
