Former welterweight champion Kell Brook believes rising top contender Jaron Ennis is potentially the fighter to overtake the scene at 147-pounds.

On Saturday night, unbeaten fighters Errol Spence and Terence Crawford will collide to crown a new undisputed world champion at the T-Mobile Arena in Las Vegas.

Based on his recent performances, Brook really likes what he sees from Ennis.

"He is looking good, so good that he could be the one to succeed [Spence and Crawford]," Brook said to Metro.co.uk. "He has great ability, punching power and like these guys, massive boxing IQ. I put him up there in the elite, among the best in the world.

"We don’t know for certain [how good he can be] until he gets in there with someone better or equal to himself and we see how he responds, how he takes a shot and deals with pressure on a big stage. That is when we know when a fighter has a real X-factor, when they can tie in all those qualities with the ability to do on that highest level."

As far as this coming weekend, Brook knows both boxers very well - as he faced both.

He suffered a fractured orbital bone and was stopped in eleven rounds by Spence in 2017. Three years later, he was stopped by Crawford in four rounds.

"I was one of those who worried we might never get this fight on. Now we have two of the best in the game and whoever wins is going to be the pound-for-pound no1 in any division. It is going to come down to who has got the best game plan, who has prepared the best for the other man and who will deal with the pressure. Because believe me, there will be huge pressure on both of them," Brook said.

"Errol Spence is a very big, very strong welterweight, he goes to the body well. He’s very stand up, a serious top fighter in every department. The only thing that is maybe against him is being inactive in recent years, dating back to the car crash. That will play a factor in this fight."
