Lennox should fight Tyson next to silence the American public who have never given him the respect he deserves. After that, win or lose, he should retire.

That's an interesting point. I spoke to Bernard Fernandez, who's the boxing correspondent for the Philadelphia News, and he said that there is no point in Lennox Lewis fighting Mike Tyson, and that he should retire now. He also said that Lewis has got nothing to prove, and described Mike Tyson as a 35-year-old who trains in lap dancing clubs.

He also said that Lewis does not always give you the total package, but he certainly did that against Hasim Rahman on Saturday. Fernandez was fairly convinced that Lennox Lewis is one of the top ten heavyweights of all time, although he was also convinced that he didn't enjoy watching him very often!

My view is that Lewis should retire now - he's got nothing to prove, and he's made so much money. A fight with Mike Tyson might have been great for him four or five years ago, because both men were closer to their prime. Now, they're both one or two fights away from retirement, and I think it's a not a big a fight as used to be.

Lewis would be wise to take the glitz accompanying a Tyson fight rather than defend against the impressive and dangerous Vladimir Klitschko.

I disagree. The thing about Klitschko, both Vladimir and his brother Vitali, is that they are big, tall, decent fighters who are somewhat scary because of their size. If you look at Lennox's record, and the people he has beaten - the likes of Michael Grant, Andrew Golata and Henry Akinwande - he loves fighting people that are bigger than him. I think in those situations he fights a little bit with fear, because it's rare for him to be the smaller man.

I don't think Klitschko would provide much of a challenge. Both the Klitschko brothers have been beaten, without winning anything of note. It would also be a very difficult fight to sell to the British public, because we don't know anything about him.

How can Lennox Lewis be regarded as a 'great' boxer, having been knocked out by both Rahman and McCall?

There are an awful lot of people who think like that, and for whom nothing that Lennox now does can change that. And they've got a point, because Oliver McCall stopped him in two rounds and Rahman in five. So he's suffered one-punch knockouts, which show that perhaps his chin isn't the best in the heavyweight division.

If you look at the greatest boxers of all time - Muhammad Ali, Joe Lewis, Rock Marciano, Jack Dempsey, Larry Holmes, and perhaps even Evander Holyfield - they all had very strong chins, and they didn't ever suffer that kind of early knockout.

But what you also have to remember about Lennox Lewis is that he's fought just about everyone, and he's beaten everyone. I personally don't enjoy watching Lennox Lewis fight. I was a teenager when I saw him fight Razor Ruddock at Earls Court. He stopped him in two rounds and that was a very exciting night. But I've had to wait a long time before I was that excited again, and when I was it was on Saturday night against Rahman. I think Lennox deserves a place in the top 10 heavyweights of all time, and I'd go as far as to make a case for him being in the top five.

Watching Hasim Rahman sprawling on the canvas having been totally outclassed, reminded me of other 'one hit wonders' such as Buster Douglas. Is there any back for Rahman? Or will he now slide quietly into obscurity?

There is a way back. I think Don King summed it up in the press conference when he was talking about Oliver McCall fighting Henry Akinwande. He said they'd 'resurrected the dead' and 'Lazarus had returned'. Rahman now falls slightly into that category of fighters who are, more or less, nowhere. I think he can be re-marketed and re-packaged, but he must remember that as likable and charismatic as he is, he made his name as a fighter, and not as a talker.

I think a few of us alluded this week to fact that he was perhaps getting carried away with his own press. He's a decent fighter who got as far as he did by over-achieving - he's made more money from this one fight than he did throughout his whole career. He can come back, because the heavyweight division at the moment is poor, and there aren't that many great fighters out there, and the best ones - Tyson, Holyfield and Lewis are all over the age of 35.

Rahman did say earlier in the week that he was looking to get out of boxing in his early thirties, and he didn't want to be known as someone who took too many fights. He's 29 now, so if he did come back, that would be interesting.

It would have been a double celebration for Britain in Las Vegas, but for the scandalous decision made by the judges in the Howard Eastman v William Joppy fight. How Joppy got the win is beyond me. Is there any way that Eastman can appeal against this appalling decision?

He can appeal, although I don't think he will, because that's not his nature. At the time I found myself to be in the minority of people who though Eastman had won - I scored the fight unofficially and made Eastman a five-point winner. I've spoken to a lot of Americans who share my view, but it actually seems to be the British press who don't think he won. I was very impressed with Eastman. He did things that perhaps we didn't think he could do and he took punches we didn't think he could take.

He controlled the fight, landed the better the punches, and all this against a guy (William Joppy) who is an exceptionally good fighter - one of the most talented American fighters out there. I spoke to Eastman afterwards and he said that he felt he was robbed, and that maybe it was something to do with the fight being in America. I don't think we've seen the last of him, and if people realise what a marketable and charismatic guy they've got on their hands, Howard Eastman could fill the void soon to be left by the likes of Lewis and Naseem Hamed.

If Eastman gets a re-match and wins it, he could then take a fight with Bernard Hopkins - who is really the middleweight champion of the world, and another hugely charismatic man. If those two fought in London, you're talking about a massive fight.
