Amir Khan says Kell Brook is not as good - or as well-known - as Devon Alexander

Amir Khan believes Devon Alexander is going to be a tougher test than British rival Kell Brook.

That fight will always be there for me but it has to happen on my terms because I’m the name going into that fight even though he has the title

The welterweight takes on the two-time world champion at the MGM Grand, Las Vegas, live on Sky Sports 1 next weekend.

Khan is of course linked with an all-British showdown with Brook but wasted no time telling the IBF champion he is not only behind the likes of Floyd Mayweather or Manny Pacquiao, but is less of a threat than his opponent on Saturday.

"I think this Devon Alexander will be tougher," he told Sky Sports.

"I think in a fight with Kell you're looking for his shots more, you're waiting, being more patient. It's not going to be explosive. A fight that is not going to work you hard.

"The workrate is going to be low but against Devon it is going to be high. I also think Devon has better footwork with his angles. I think his fight will be tougher.

"Styles make fights and they will make a tough one, too."

Name

Brook will be back in the ring in March, not only to make the first defence of the title he took from Shawn Porter in California but to show he has recovered from a shocking stabbing in September.

Khan has not boxed for six months himself and admits that the pair will eventuall fight - and wants it to be at Wembley Stadium - but later, rather than sooner.

"Brook is not one of the biggest names," he said.

"That fight will always be there for me but it has to happen on my terms because I’m the name going into that fight even though he has the title.

"Hopefully he keeps hold of that title because it makes the fight bigger. In a couple more fights I could be a world champion then it would be a unification fight. 

"But first I’ve got Alexander, then one of the pound-for-pound best, then we’ll see."
