Wladimir Klitschko has admitted that he is still stunned after losing his heavyweight titles to Tyson Fury in Dusseldorf on Saturday.
The Ukrainian was beaten by the 27-year-old Brit on a unanimous points decision.
The 39-year-old, who relinquished his WBA, WBO and IBF belts, had not lost in 11 years prior to Saturday's showdown.
On Monday, Klitschko tweeted: "I still don't believe I actually lost. Man, I'm suffering."
Fury's uncle and trainer Peter has claimed that a rematch between the two boxers could be held at Wembley in May 2016.
