Former world champion Amir Khan (31-4, 19 KOs) is looking to prove everyone wrong in his latest comeback to the ring.

Khan has been away for nearly two years. The last time he saw action was in May 2016, when he moved up to a catch-weight of 155-pounds and was knocked out in six rounds by then WBC middleweight champion Canelo Alvarez at the T-Mobile Arena in Las Vegas,

Khan, who signed a three fight deal with Eddie Hearn's Matchroom, will return to the ring on April 21 in a welterweight clash with Phil Lo Greco.

According to Khan, his ring return is not about the money. He made a decision to return to the ring in order to further his own legacy and show that he still has the skills to compete with the best fighters in his weight class.

"If I stop now I've still had a great career," Khan told Sky Sports News. "I've won world titles, the WBA 'Super', the WBA and the IBF, but I want to do it because I love the sport. I know there is more left in me. I can call it a day and do something else but I love the sport so much, and I know I can do a little bit more."

But there have been many calls for Khan to retire from the sport, including advice being put out there from close friend Ricky Hatton, who feels Khan should think twice before staging a ring return.

Hatton made a failed comeback bid a few years ago, and saw himself get knocked out in his return.

"Ricky is coming from there because a lot has happened in my life in the last couple of years, so he maybe thought I should just call it a day," Khan said.

"But I've surpassed that now so it's now time to put all that behind me and move forward. I always said from day one, I am going to be the one that walks away from boxing. I am not going to let boxing retire me, I will retire from boxing. I might wake up one morning and think 'you know what, I don't want to do this anymore', but at the moment I am waking up every morning wanting to be a champion again."
