It's a possibility - but it is a big, big ask.

Denise Lewis - is this her year?

Dwain did superbly to take bronze at the World Championships, but the men who beat him that day - Maurice Greene and Bruny Surin - are still around and still running faster.

Add to that list Ato Bolden and emerging American Brian Lewis and you have a mighty strong field.

A medal of any colour would be a great result for Chambers.

Katharine Merry400m

Almost from nowhere, Merry has arrived as a world-class runner.

Aussie Cathy Freeman remains favourite for gold, but is under immense pressure from her home crowd.

And at the rate Merry is improving, there's no telling what times she might be running come September.

Jonathan EdwardsTriple jump

On paper, Edwards is right up there. Still the world record holder, on his day he is capable of out-jumping anyone in the world.

But, in the past, he sometimes has not delivered when it really mattered.

He came only third in the last World Championships and took silver in Atlanta when red-hot favourite.

Came a poor fourth in the Rome Golden League meet, but if he can get his technique spot-on, he will threaten.

Denise LewisHeptathlon

After bronze in 1996, silver in the last two Worlds and gold at the 1998 Europeans, Lewis is primed to take the big one.

Injuries are the key. If she can get an entire season under her belt before Sydney, her chances are good.

The technique and natural ability are there in spades.

Steve BackleyJavelin

The old stalwart of the British team returns again, but at 31 and after a year of technical problems, it is to a much tougher game.

He took silver in 1996 but, after dominating in the early nineties, has struggled to hit those peaks again.

An outside bet if his aching frame stays in one piece.

Ashia HansenTriple jump

The ability's there, as Ashia showed in taking the World Indoor crown last year.

Jonathan Edwards jumps for gold

But can she put it together when it matters? In the last World Championships she could not. In the last Olympics, she so nearly did, coming in fourth.

After a dismal start to the year on the home front, with her ex-boyfriend Chris Cotter on bail and facing three charges relating to an alleged racist attack, her training was seriously disrupted.

But she remains in with a shout.

Men's sprint relay squad4 x 100m

Britain now has an accomplished pack of young sprinters, equalled only by the USA - and that balance may be swinging in the UK's favour.

Put Jason Gardener, Darren Campbell, Marlon Devonish and Dwain Chambers together and you have a real threat to the American dominance of this event.

Paula Radcliffe10,000m

Put in a memorably gutsy performance to take silver behind Gete Wami at the World Championships last summer, and remains one of the outstanding athletes of her generation.

But does she have the finishing kick that a gold medallist should have?

Reaching her peak and now happily married to former 1500m man Gary Lough, this is the summer we will find out.

Dean MaceyDecathlon

Came from nowhere to claim silver in the World Championships, his first senior appearance in a GB vest.

On that occasion he set six personal bests, and should he show anything like the same form again, he is in with a solid medal chance.

If he beats that number of personal bests in Sydney, gold could be the colour.

Iwan Thomas400m

It all comes down to injuries and a superman. Injuries being what stopped Iwan from training properly last winter, and the superman being Michael Johnson.

Iwan's now fit and has started the season well.

Trouble is, so has Johnson. Still, the American has got to be beaten one day.
