Not sure about this being such a wise move after 4 years out of boxing and being 38 years old?

Always loved watching Kessler - True warrior who more than proved he was world class on numerous occasions.

He must have surely earned some serious money so he's either skint or genuinely just can't leave it alone and seriously fancies himself against Degale, Ramirez and Zeuge.

If he's still in decent shape you'd have to give him at least a punchers chance against any of the current belt holders.
