IBF, IBO, WBA heavyweight champion Anthony Joshua - during the Sky Sports program 'AJ - History In The Making' - said his street mentality pulled him through in the April showdown with Wladimir Klitschko.

Joshua (19-0, 19 KOs) dropped Klitschko in the fifth round, but the veteran came roaring back by the end of the round and then dropped Joshua in the sixth. After some tough rounds, it was Joshua who rallied down the stretch and stopped Klitschko in the eleventh after two more knockdowns.

The fight was held at Wembley before a record crowd of 90,000 fans.

It's no secret that Joshua ran with a rough crowd as a teen and his some troubles, before he got his act together and became a talented amateur who went forward to win Olympic gold in 2012.

That rough upbringing, says Joshua, made a big difference when the going got tough in the contest.

"He's very intelligent, he's got a PhD, but you ain't got that hustle like me," Joshua said. "As soon as the fight was stopped, I smiled. I said to myself 'you can't out hustle me'."

Joshua praised Klitschko for the huge shot that decked him in the sixth round, but says it wasn't big enough to keep on the mat for good.

"It was a big shot, but it wasn't enough to keep me down," said Joshua. "It put me down, it didn't keep me down. The shots that I feel are just when I'm being lazy. With him, I didn't even see it coming. It was a sweet shot."

There is a rematch clause in the contract and both sides are discussing the possibility of a second bout in the fall. Joshua's promoter, Eddie Hearn, recently flew to Las Vegas to hold a meeting with executives from MGM and took a tour of their newest facility, the T-Mobile Arena. Joshua and his team are waiting for Klitschko to make a final decision regarding the rematch.
