Tyson Fury has vowed to win the rematch against Oleksandr Usyk.

‘The Gypsy King’ lost to the Ukrainian last month when he was defeated via a split-decision verdict from the judges.

This week footage had emerged of the former WBC heavyweight champion being escorted out of a pub before falling flat on his face outside.

But, today he released a new video on Instagram and has sent the undisputed champion a warning.

In the post he wrote:

‘Listen up! I’ve conquered everything in boxing – titles, records, the lot. But I’ve never had to come back from a loss.

On December 21st in Riyadh, in the heart of the kingdom, the king will reclaim his throne and become undisputed. @usykaa , I’m coming for you! Get ready for the Gypsy King!

The path to redemption is all mine. I know what I have to do, I saw my shortcomings and best believe I am inevitable.”
