Former world champion Amir Khan (31-4, 19 KOs) has his sights set on showdowns with fellow ex-beltholders like Kell Brook and Manny Pacquiao in the future.

For the first time in nearly two years, Khan will enter the ring on April 21, when he faces Phil Lo Greco in a welterweight contest from the Echo Arena in Liverpool.

The contest will be the first of a three-fight agreement that Khan signed earlier this year with promoter Eddie Hearn of Matchroom Sport.

The last time Khan entered the ring, it was back in May of 2016, when he moved up to a catch-weight of 155-pounds to challenge then middleweight champion Canelo Alvarez.

Khan started off well, but he was knocked out in the sixth round at the first ever boxing event to be staged at the T-Mobile Arena in Las Vegas.

Provided everything goes well against Lo Greco, he is hoping to have his second fight in coming months against a major name.

The biggest money fight for the Bolton boxer would be against Brook - but that would require a catch-weight as Brook recently moved up to the junior middleweight limit of 154-pounds.

As far as Pacquiao, who at one time was Khan's training camp stablemate when they were both coached by Freddie Roach, he is scheduled to return on July 15th in a showdown with WBA 'regular' welterweight world champion Lucas Matthysse in Malaysia. However, Pacquiao is talking about a fight with Vasyl Lomachenko in the fall.

"I’ll get the Lo Greco fight out of the way. I’m not looking past it but I want to slowly step up and maybe in the future get like a Manny Pacquiao or Kell Brook," Khan told TalkSport.

"These are the fights I want now. It’s all about cleaning up the sport and finishing on top and winning another world title."
