JONNY Wilkinson believes Wales could be the side to watch in the RBS 6 Nations Championship.

England needed 23 points from the boot of their inspirational fly-half to secure a shaky World Cup quarter-final victory over Steve Hansen's men at Suncorp Stadium in Brisbane in November, where they were outscored by three tries to one.

Wales had also given New Zealand a run for their money in the final Pool D match - and Wilkinson is in no doubt Sir Clive Woodward's side will face a tough challenge when the two countries meet at Twickenham for their 2004 Six Nations showdown on March 20.

"In the World Cup we had direct contact with Wales, so we know a lot about them. The way they are playing at the moment is fantastic," said Wilkinson.

"They are there on merit and other teams have got to play well against Wales.

"They have made a statement by the way they played in the World Cup to say 'we could have beaten New Zealand and we could have beaten England'.

"So they are there, and France again - who were favourites for the World Cup at one point. "I think everyone tends to play well against us anyway. Every team has got a bit of an image and pride to guard, but that is the way it is - you are judged on your last performance.

"We have got to make sure that after these next two weekends that we are continuing to move on a positive, upwards, curve."

England may be world champions, but the man who famously drop-kicked his country to glory Down Under last year knows everyone will now be out to bring England down a peg or two.

And rather than resting on their laurels, Wilkinson maintains England will go all out to ensure they continue winning.

He said: "It took a huge effort from everyone in the team to win the World Cup and we all pulled through and I think everyone should be proud of being able to say, however many times, that they were there.

"What I am more scared of is that you might have to say I was there when we let ourselves down in the Six Nations, or we had a bad tour.

"That is the sort of thing I fear having to talk about for the rest of my life, the missed opportunities - and that does scare me a bit.The important thing is we get another medal to add to the pile."

Wilkinson has managed just 58 minutes of rugby since returning from Australia as he continues his rehabilitation from a niggling shoulder and neck problem.

He has already been ruled out of England's Six Nations opener against Italy in Rome on February 15, and admits lack of action has become frustrating.

He said: "If there was a time scale, you could at least say 'I know where I am heading for,' but as it is it has just been a case of 'it could be'."
