David Haye, also speaking to Radio 5 live: "I've knocked out guys a lot bigger and stronger but he has the heart of a lion.
"I gave it my best and it wasn't good enough. He was by far the better fighter tonight. He dug deep and took my best shots and put me down.
"I would love to do it again, I have never been in a fight like that. If the fans want to see it again I would do it again. We'll do it on his terms, in his town - he deserves it."
On his injury he said: "The ankle was just one of those things. The better man won on the night.
"It wasn't my night. I didn't land the good shots, I was in good shape but his game was better than mine.
"It felt like a Rocky movie and I was one punch away from knocking him out but I couldn't quite do it."
