Lewis has suggested that Audley has more than enough in his locker to knock out David Haye and has warned against complacency. Lennox Lewis knows only too well what a shock punch can do to you when it lands, having lost to American Oliver McCall at Wembley, going down to a sucker punch.
Although Haye is a favourite, David must not underestimate Audley.
"Audley realises this time is now or never," he said. "He sounds very confident.
"Audley's definitely got the power to stun the world and upset everybody's thinking. It's another great fight for Britain
"It will be a good fight. I think David Haye is a better boxer. He can get off his combinations quicker. But Audley is a consummate pro. He is an Olympic champion and that is a great pedigree."
Lewis doesn't subscribe to the view that Harrison lacks heart.
He said: "OK, there have been a couple of stumbling blocks. But he is still here. That shows he has the desire to succeed."
