AMIR Khan is promising to deliver another explosive performance when he takes on Samuel Vargas at Arena Birmingham on September 8.

Bolton's former unified world champion returns to action following his blistering return to the ring in April in Liverpool where he destroyed Phil Lo Greco in just 39 seconds after nearly two years out of action.

Speaking from his Los Angeles training camp, Khan said he will need to beat Canadian-based Columbian Vargas in style if he is to secure a shot at welterweight world honours later this year.

"Fans will see another explosive performance on September 8," said Khan.

"I didn't get a chance to show everyone what I had been working on during my time out against Lo Greco.

"But you saw the punch power, accuracy, speed and timing and you'll see it again against Vargas.

"I always make it exciting, it's going to be another big bang.

"Vargas is another step and move in the right direction. This will take me on to the bigger and better fights."

Khan is approaching his second fight under vastly-experienced trainer Joe Goossen and is confident the extra time he has spent in the gym will benefit him greatly come fight night.

He added: "The bond is growing with Joe, we’ve had much more time to work on things in this camp.

"We’ve been improving what Joe sees as my strengths and also the mistakes I can make in a fight so we’re building to become the full package."

Khan’s clash with Vargas tops a packed card in the second city which also includes Bolton super bantamweight Osman Aslam.
