Parker defends his WBO world heavyweight title against Fury in Manchester on September 24 .
He has arrived in London to fine-tune his preparations before transferring north next week.
With just one fight this year, Parker is refreshed and eager for action. He's also been able to shrug off the shoulder and elbow problems that hampered him during a busy 2016.
R"My mind is clear; my body is in great shape. I want to smash this guy," Parker told Stuff from London.
"I can seriously say I feel the best I have felt in my whole career.
