Wladimir will face Anthony Joshua with the IBF and WBA heavyweight titles on the line on Saturday night in front of a 90,000-strong capacity crowd at Wembley Stadium.
However Lewis, who preceded Klitschko as the finest heavyweight of his era and fought in Europa, Africa, and throughout the USA, is adamant it is the responsibility of a true world champion to fight across the planet and that that is what Joshua should do.
ANTHONY JOSHUA is leaving no stone unturned as he prepares to fight Wladimir Klitschko on Saturday - even resorting to a freakish ancient muscle treatment.
Anthony Joshua has claimed that he can not simply rely on his strength when he takes on Wladimir Klitschko in a huge heavyweight showdown on Saturday.
Vitali Klitschko expects his brother Wladimir to beat Anthony Joshua because he knows he has "no second chance" in the twilight of his career. Not to wait, to come in and show his performance.

The Socialist and previous centre-right administrations had "done everything to ensure that we lose" the fight, she said . Other US presidents have weighed in - some directly, others more obliquely - on foreign elections in the past.
"I see on social platforms and social media that he's working out and he's a disciplined fighter, a likeable guy".
"I just look at little parts of it, not the whole thing".
Anthony Joshua has told Wladimir Klitschko his mind games are transparent, although the Briton is wary of facing a wounded animal at Wembley. "I am more focused on myself and my ego; I don't care about Joshua and Fury or whatever dog fight he got into". Come here. Come and fight us.
"She is confident enough in me to watch, but I would rather she not be there". He enters this Saturday's contest as the betting underdog against the 2012 Olympic gold medalist, but you most certainly can't count him out of this matchup. I think these guys respect each other too much to try to be a hero.
Joshua believes the status quo of boxers needing to head to America to earn their stripes is no longer the case and that his reputation can be enhanced in his own backyard. You can throw those same fighters inside the ring with Deontay Wilder, Joseph Parker and Luis Ortiz and they would all likely be knocked out. I don't want him to hold back because Fury was bigger than him or this and that.
