Vitali Klitschko believes Anthony Joshua’s muscles will be meaningless against Wladimir Klitschko’s boxing brain.
Joshua has displayed his physique on social media ahead of his bout against Wladimir at the Wembley next month.
Vitali believes his younger brother’s 68 bouts is more than enough to better the undefeated British boxer who holds the IBF belt.
“Many people think muscles are important in boxing,” Vitali Klitschko told Sky Sports. “It’s not. Everything is here, in the head.
“He’s much more focused right now than many years ago. I hope he knows from his focus, from his concentration, that this fight depends a lot and that’s why everyone expects a great fight.
“Yes of course we expect a good performance from Wladimir and yes of course Wladimir has to be the winner on April 29.”
Klitschko will face the unbeaten Joshua in front of 90,000 at the national stadium, but Vitali believes this red-hot atmosphere could prove more unsettling for the home favourite.
“Wladimir has already big experience of fighting in an arena,” he said. “He’s used to fighting in a stadium, pressure from the crowd, from attention.
“It will be something new for Joshua and nothing special for Wladimir.”
