Former world champion Amir Khan (33-4, 20 KOs) is hoping to get a mega-fight with either Manny Pacquiao or Kell Brook.

At only 31, Khan is still at a young age but he wants to retire in the next few years.

Khan has fought twice in 2018, and aims to fight for a third time before the year is over. He blasted out Phil Lo Greco in less than a minute in April, and then earlier this month he won a tougher than expected decision over Samuel Vargas.

The biggest fight of Khan's career was a 2016 showdown with Saul "Canelo" Alvarez, who at the time was the WBC middleweight champion.

Their HBO Pay-Per-View fight was the first boxing event at the T-Mobile Arena in Las Vegas.

Khan started off well, but got knocked out brutally in the sixth round.

"If I leave this sport having not fought either Kell Brook or Manny Pacquiao, I will only have had one big fight against Saul 'Canelo' Alvarez. I went up two weight categories and gave too much away, because I thought it would make me a star. I want a big fight to show the world that I belong at the top," Khan told Sky Sports.

"Then I will finish and be happy to walk away, knowing that I've given my fans everything that I have. It will be on my terms. I swear, this is what burns my energy. I want to burn my energy in a positive way. I love that people like me because of my boxing. Why should I leave?"

This is why he wants Pacquiao or Brook - if not both.

But he admits, that against that level of competition he can't afford to get dropped as he did in the fight with Vargas or in some of his past performances.

"With me, the problem is not punch resistance. It's about not being in the right position to take a shot. Some fighters are so focused about staying in the right position when they get hit. I'm so quick and light on my feet that, sometimes, I can get hit," Khan said.
