Former undisputed world heavyweight champion Wladimir Klitschko (64-4, 53KOs) is staying in shape and he's fully focused on a rematch with Tyson Fury (25-0, 18KOs).

The two boxers faced off last November in Germany with Fury winning a twelve round unanimous decision in what many considered to be the "2015 Upset of The Year."

The victory gave Fury the WBO, IBF, IBO and WBA super world championships.

There was a contract clause that mandated an immediate rematch. Klitschko wasted no time in exercising that clause to get revenge.

The rematch was reportedly targeted for May 7th - until Amir Khan finalized his fight with WBC middleweight champion Saul 'Canelo' Alvarez for the same date in Las Vegas, Nevada.

The rematch would very well take place in the UK in June.

According to the Manchester Evening News, one of the frontrunner venues is the Manchester Arena with a tentative date of June 4.

While Klitschko has said very little about the fight, he took to the social networks on Tuesday to post a message to his followers.

"Many of you have been asking - the rematch against Fury is still in the making. I will keep you posted about the time and place. Meanwhile, I’m keeping up my routines to stay in shape. ?#‎ImTheMovingForce," Klitschko wrote.

Fury still holds three of the remaining world titles. The IBF title was stripped away for failing to make a mandatory defense against Czar Glazkov- who was later stopped in three rounds by Charles Martin for the vacant belt. Martin defends that title next month against Fury's countryman Anthony Joshua.
