Anthony Joshua claims he watched his fight with Oleksandr Usyk and learned from it.
Joshua, who will face Usyk in a rematch in the coming days, also stated that he had recognized his flaws.
The 31-year-old lost his IBF, WBA, and WBO heavyweight titles to the Ukrainian last Saturday at Tottenham Hotspur Stadium in London.
Joshua said in an Instagram post on Thursday that he had also analyzed his preparations and told his fans not to worry about him.
“I’ve watched the fight, analyzed my preparations, and identified my mistakes,” he wrote. “I’ve learned my lesson,” he said.
“Many thanks for your love and for checking in.
“Don’t be concerned about me. My spirit is powerful.
