Former champion Amir Khan (31-3, 19KOs) is now looking to return to the ring in November or December.

Khan was chasing a lucrative fight with WBC/WBA welterweight champion Floyd Mayweather Jr. on May 2nd at the MGM Grand in Las Vegas.

It now appears Mayweather will be facing former IBF/WBC beltholder Andre Berto.

Khan is mapping his 'Plan B' opportunity, but his opponent won't be IBF welterweight champion Kell Brook (34-0, 25KOs).

The fight between Khan and Brook is a huge blockbuster in the UK - but Khan believes the fight could be much bigger - if Brook fights a higher level of competition unlike his recent bouts with Jo Jo Dan and Frankie Gavin.

"All he has to do is face some top names, like Bradley, Maidana and Thurman," said Khan to The Mirror. "I proved myself by going in and fighting guys at their peak, but with him, he's not doing that. Instead he's fought Jo Jo Dan and Frankie Gavin in his last two fights. Why not prove himself?

"One thing about me, is I'm not scared of anyone and I've never said no to a fight. The only reason that fight isn't happening is because my team advise me it's not the right time to do it yet and that it could be a bigger fight. He would not be able to sell-out Wembley. The only fight that could sell-out Wembley would be me against Mayweather or Pacquiao. Kell Brook is not big enough yet to sell-out Wembley.

"I've topped bills at the MGM Grand Garden Arena. Kell Brook could walk down the Strip and no-one would recognise him. If he builds himself up like I did, then there would be two super, mega names. It would be a like a Mayweather-Pacquiao and the numbers would be big around the world. Why make it a fight for £5million-£10million when it could be a £100million fight?"
