Croydon boxer Wayne Alexander believes he is in the best shape of his career ahead of his fight with Frenchman Serge Vigne at the Excel Arena, Docklands this Saturday.

Alexander (pictured), the WBU light-middleweight title holder, is hoping to use the bout as a warm-up for a shot at Sergei Dzinziruk's more prestigious WBO title early next year.

Vigne, has won 20 of his 37 professional fights and shouldn't pose too many problems for Alexander, but the 33-year-old is leaving nothing to chance.

Having spent four months locked away from his four-year-old daughter Sade in a Belfast training camp, the Croydon man is raring to go.

"No fights are comfortable, I've been training extremely hard," declared Alexander.

"I wasn't in the best of shape, but I have run more than 300 miles in the past four months and am definitely in the best shape of my career.

"Serge is no mug - he is an established fighter who has lost a few against good boxers, but I am ready to go."

The fight is on the undercard of a impressive bill topped by troubled Scotsman Scott Harrison, with Audley Harrison facing Danny Williams and Amir Khan also in action.

"It is the biggest show of the year," said Alexander.

"Hopefully I will get a TV slot to help raise my profile. My last fight, against Thomas McDonagh in March, was on ITV, but he stunk the place out and ran away for 12 rounds.

"I want to put on a good performance and show what an attacking fighter I am."

A win would set Alexander up for the biggest fight - and payday - of his career against the unbeaten Ukranian Dzinziruk, possibly in Germany, where the WBO champion is based.

"He is a very good fighter, but I want to win the title and go out at the top," said Alexander.

"I have only got two years left and am planning a maximum of 10 more fights. Duke McKenzie was a world champion, but I want to be Croydon's first two-time world champion."
