Now that the next defence of my WBO world super-middleweight title that I told you about three weeks ago has been confirmed, it's full steam ahead again.

My 14th defence will be against Armenian No 1 challenger Mger Mkrtchyan in a mandatory defence at the Welsh National Ice Rink.

And I'm predicting another knock-out to follow the one against American challenger Byron Mitchell last time out, though it may take a little longer.

I don't know anything about Mkrtchyan, which is something I don't like, but by the time of the fight I'll have got some tapes and be well prepared.

And that preparation has already begun, which means the training.

I'll be training twice a day, six days a week to begin with. That means five mile runs in the morning with some sprints mixed in and 12 rounds of gym work in the afternoons, including bag work and pad work.

It's four weeks of hard sparring, probably with stablemates Nathan King and Bradley Pryce and a few boxers brought in from England.

That drops off the week before the fight when it's not so intense and it's back to speedwork to keep ticking over, a bit of jogging and shadow boxing in order to make the weight.

Of course I also now have to concentrate on my diet, which means a high carbohydrate, low fat intake and reducing the amounts gradually.

I train the same for every fight. If it ain't broken, don't fix it is my motto.

I treat all my opponents the same and that way they all go the same way - defeat.

One thing I'll be laying off is sticky sweets, a bit of craving of mine.

It was because I'd been eating them that a gold cap came off a tooth for about the third time last week and I had to go to the dentist. That meant me being late for a Press conference.

Then I got a bit embarrassed when promoter Frank Warren kept referring to me as the sexiest man in Wales and my boxing friends started ribbing me.

That was the result of a poll in a national newspaper, which I just regard it as a bit of fun.

But I suppose it's not bad that someone who has been boxing for 21 years can still win a poll of that sort.

Tomorrow it's the big rugby match, which Wales will win. But that will be the end for Wales because they have no chance of beating England in the quarter-finals. It's arrivederci from me.
