Wladimir Klitschko can’t be serious about comeback … can he?

Klitschko, 43, kept alive speculation about a comeback, asking fans on Twitter what they thought about him fighting a top heavyweight.

Rumors about a Wladimir Klitschko comeback aren’t going away, in part because Klitschko won’t let them

Klitschko, 43, kept the speculation alive Saturday on Twitter, asking fans what they thought about him fighting Anthony Joshua, Tyson Fury or Deontay Wilder.

Klitschko, retired since Joshua stopped him in the 11th round of a bout on April 29, 2017 at London’s Wembley Stadium, posted three Tweets.

In the first Tweet, he said: “Let me entertain you with this and you can like it or not: Fury vs Klitschko 2.”

Fury’s claim on the lineal heavyweight title is based on his unanimous decision over Klitschko, then the unified champion, on November 28, 2015 in Dusseldorf, Germany.

He followed with a second Tweet, substituting Joshua for Fury.

In the third, he subbed in Wilder and deleted the 2. Wilder, who holds one of the heavyweight belts, and Klitschko sparred. But they never fought.

Klitschko (64-5, 53 KOs over a 21-year career) retired after successive losses to Fury and Joshua.
