The Gypsy King put his WBC belt on the line against the Body Snatcher on Saturday night in his first fight on UK soil since August 2014.
Fury dictated the tempo right from the start before ending proceedings in devastating fashion.
And after the fight Fury told his wife Paris, who was sat ringside, that he would retire from boxing.
However, Lewis wants to see him fight at least one time before he officially calls it a day, as he insists there is still some ‘unfinished business’.
He wrote on Twitter: “Another great performance by Tyson Fury last night to show why he’s the number one HW [sic] in the division right now.
“But let’s talk about the economics. He filled Wembley with 94 thousand fans (the biggest gate in Wembley history) to prove he has drawing power among UK fan base.
“So to think, that there’s even BIGGER [sic] fights than this still out there is [mind-blowing].
“I know he’s talked retirement after last night, but I feel there’s still some unfinished business to be done on his part and I look forward to welcoming him into the undisputed club as a fellow Brit and as an honour to the lineage of Kronk Boxing, when all is said and done.
“To see him get up off the canvas of life and turn himself into the best HW [sic] in the world is a thing of beauty.
“I’ve personally learned to never bet against him and am proud of his accomplishments and commitment to himself and his craft.
“When Anthony Joshua and Deontay Wilder had a chance to make history, it didn’t happen.
“Fury is one fight away, and either, AJ or Usyk, are 2-3 fights away from UNDISPUTED. Which is the fight I’ve been calling for for many years.
“I’m hoping everyone takes care of business and the winner of Joshua-Usyk steps into the ring with Fury to crown the first undisputed champion since me.
“I’ve been keeping UNDISPUTED warm for way too many years.
In the meantime, it’s now time for Tyson Fury to celebrate his win with his family and friends and wait to see what happens in this crazy HW division. Congrats champ on a job well done. Relax, rest, and enjoy. All of it is well deserved. Bless!”
