As WBN reported on Saturday, Joshua is on the verge of leaving Wilder behind in favor of a clash with Alexander Povetkin in September, a move which will disappoint many boxing fans around the world.
Should Joshua have a late change of heart and come together with Wilder to find a solution to the deadlock, Klitschko says the Briton can firmly enhance his reputation.
“The question always when there are many world champions is: who is the strongest one? – That’s why to fight Wilder is very good. Right now Joshua is a champion. With this fight, he can be a star,” Klitschko told The Guardian.
On taking his own career to new heights, Klitschko added: “Sports gave me the strengths I use every day.
“For one, it’s very important to have a good team around you. Early in my career I was told if you want to be the best in the sport, take the best coach, take the best promoter, take the best manager, take the best lawyer and with the best team you will be automatically be the best.
“Exactly the same. I’ve tried to find the good people, good people who will take responsibility. Because as Mayor (of Kiev) no matter how strong you are yourself, no matter how big muscles you have, alone you can do nothing. You need good people around you.
“Secondly, you have to know exactly where to go. To have the will and to have courage to arrive there. That’s exactly the same way I approached my boxing career,” he added.
Joshua v Wilder is without doubt the biggest fight in world boxing right now and both sides have been encouraged to strike whilst the iron is hot.
A nine-figure Pay-Per-View extravaganza in the United States has already been ruled out by Team Joshua, whilst a counter-offer for Wilder to travel to the UK has proven fruitless.
