Anthony Joshua has admitted that he must cut out the mistakes if he is to keep his unbeaten record intact.
The 26-year-old came through his biggest test yet against Dillian Whyte on Saturday evening by claiming a knockout victory in the seventh round.
Joshua, who has now added the British title to his Commonwealth crown, endured a tough second round when taking a left hook which left him vulnerable to his rival.
Having come through that minor scare relatively unscathed, Joshua went on to keep up his perfect knockout record - which now spans 15 bouts - alive and well.
Speaking to Sky Sports News after the fight at London's O2 Arena, he said: "It was a tough fight. I made it tough for myself but that's what I need. I'd be happy to rematch Dillian because I need the experience. He came out and gave me rounds. I learned a lot. Now I can look forward.
"There were mistakes in there I can't take to the top level. That's why Dillian was perfect at this stage. I'm in no rush and I'm going to keep on building until I make my mark in this division. It's not about the rivalry. I knew I had the strength to knock him out so I went for it when I saw him hurt in the first round.
"They can soak it up between one and four and then I found my way and my rhythm and started relaxing. Then I saw certain shots I could throw. Certain shots weren't working and that's why I want the 12-round fights so I can perfect what I'm doing. The same power I had in the first round, I had in the seventh and that's how I got him out of there."
Joshua could now turn his attention to compatriot and former world title challenger Dereck Chisora, who himself reigned triumphant on the same bill when knocking out Jakov Gospic.
