Former three division world champion Marco Antonio Barrera is currently visiting London. The Mexican star is a big name in the UK. Back in 2001, Barrera dominated Prince Naseem Hamed, who at the time was a huge favorite to win. The 38-year-old fighter is still upset with his 2009 technical decision loss to Amir Khan in Manchester. Inactive since 2010, Barrera would love to get Khan back in the ring, but he doesn't expect a rematch to ever take place.

Barrera gives Khan no credit for the win, claiming the British fighter used his head inflict a very bad cut, which stopped the fight. He doesn't believe Khan has what it takes to become a great champion.

"I feel very sad that I fought Amir Khan with the cut and I want one more fight to prove who I am. Amir Khan never fought with me - he only hit me with his head. He just needed my name but he never fought with me. I don't think Khan can be a great champion. He looked good in the fight with Peterson, which was a tough fight, but he cries. In Manchester when he fought with me, the commission gave him a big present when he hit me with his head," Barrera told Sky Sports.

"When he hit me with his head, I felt very bad because I know all the people love this sport and I came to give the best of me. I don't like what happened in the fight. Maybe if he hadn't have hit me in the head, the story would have been different.

"If they stopped the fight, 'no contest' should have been the decision. And there was no rematch - yet he demands one with Peterson. I would fight him again - not for Amir Khan, but for all the people here in England who want to know who Amir Khan is. He's very fast but he doesn't have a punch. He does have a head made of stone though! I respect him but he doesn't respect the people in England because he knows he didn't beat me at fighting."
