Peter's power proved to be too much for Maskaev

The 27-year-old unleashed a flurry of punches to finish the Russian off in Saturday's first ever heavyweight title fight to be held in Mexico.

Peter was the more powerful and poised throughout - although the pair rocked each other in the third round.

"I'm the best heavyweight in the world. I'm undisputed," Peter said.

"I can beat anyone. All of them are going down."

Peter improved his record to 30 wins (23 KOs) with one defeat by IBF champion Wladimir Klitschko.

And he is already eyeing up a rematch with Klitschko to avenge his loss.

"I'm going to get him," Peter said. "I'm going to beat his brother (Vitali). I'm going to tell him that I'm coming. I've got two belts. He doesn't need the IBF. He needs this one.

"He's going to come for this, and he'll get stopped."

Klitschko won a unanimous decision over Peter in an IBF heavyweight title eliminator in September 2005.
