Tyson Fury says there is no time for him to rest if he wants to fulfil his dream of becoming a world champion.
The 25-year-old won a fourth round stoppage over Joey Abell at the Copper Box to remain on course for a rematch with Dereck Chisora after the Finchley fighter won a unanimous points victory of Kevin Johnson.
The winner of that fight will be recognised by the WBO as the mandatory challenger to face Wladimir Klitschko.
But Fury, who got caught by a couple of left-handers from his southpaw opponent in the opening two rounds of their bout on Saturday, acknowledged he must raise his game in the coming months.
"I always show heart - I've got the heart of a lion," Fury told skysports.com. "I always entertain and put a show on. That's what I do at the end if the day I bring the fight to my opponent.
"But there will be no time off for me after this one because I've got a big year ahead of me. I've got some weight to lose and some tweaking up to do. I need to improve - there's always room for improvement.
"I'm back in the ring in April and I can't wait. I've got a good six months planned and hopefully at the end of that I will be in line to fight Wladimir Klitschko for the WBO championship of the world.
"I'm looking forward to it and I've been wanting it now for a while now. I'm the heir to the throne and I'm going to win because that's what I am - I'm a winner."
His trainer - Peter Fury - insists the Wilmslow fighter, will be a vastly improved fighter when he returns to the ring two months from now.
"Joey Abell was not a bad comeback opponent for Tyson after 10 months out so on the whole we're very happy with his performance," he said.
"I said it would be a knockout and he's done exactly what we expected of him. Tyson is happy to be back and he made short work of Abell.
"He's still got to get his balance right because he sometimes loses his footing and his distance right and everything else but he's on with it and away we go.
"He's going to be straight back in the gym and we're going to get some quality sparring in for him. We never brought any in for this because Tyson is at a world level now and this was just a fight to get him back going again.
"He'll fight again in April and he's got another 14lbs to shed between now and then. He's only had five weeks in camp and he's had a long lay-off.
"In April you'll see a different fighter. The timing will be there the footwork will be right and he'll be in shape. You've got to remember this was a five-week Tyson Fury."
