Kell Brook expects British rival Amir Khan to be beaten when he steps up to face WBC world middleweight champion Saul ‘Canelo’ Alvarez in Las Vegas on May 7.

IBF world welterweight champion Brook had been hopeful of securing a mouth-watering all-British showdown at Wembley with Khan this summer following some lengthy negotiations between the two camps.

However the 29-year-old Bolton fighter decided to snub Brook and move up in weight division to face Alvarez at a catch-weight of 155lbs instead.

Brook feels Khan has pulled off a bit of a master-stroke because he knows the fight will be lucrative for him, but he can drop back down to the welterweight division and continue his career if he loses.

The 29-year-old Sheffield boxer told Sky Sports News HQ: “I don’t know if he’s cashing himself in or what but I don’t believe he thinks he can win. That’s me being honest. He’ll lose in that fight.

“They can always come back down and fight the welterweights of the world. If he’d got in with me, which we all expected, I’d definitely end his career.

“Him fighting at middleweight against Canelo, he can always say ‘the guy was too big for me. I thought this and I thought that.’ He can come up with that and drop back down so it’s win-win for Khan I think.”

Brook, who is 1.04 to successfully defend his IBF title for the fourth time against mandatory challenger Kevin Bizier on March 26, added that he would be still willing to give Khan a fight regardless of how he fares against Alvarez.

Meanwhile Khan is 3.60 to win his fight, while Alvarez is 1.30 and the draw is 23.00.
