Age vs youth, speed vs experience, the showdown of showdowns comes about tonight at 10pm in Wembley stadium, London.
41-yr-old Wladimir Klitschko takes on 27-yr-old Anthony Joshua.
Klitschko is aiming to win the IBC championship for the third time after coming back from a defeat against Tyson Fury.
Meanwhile the untested Anthony Joshua wants to prove he has what it takes to swipe one of the biggest names in the modern era.
We’ll wait and see. The action starts tonight at 10pm on Sky Sports Box Office.
