JEREMY Guscott believes Wales have to consider dropping "world class" fly-half Dan Biggar to spark their attack into life in the Six Nations.

Rob Howley's side saw their title hopes ended with last Saturday's 29-13 hammering in Scotland and face a tough end to the Championship with title-chasing Ireland heading to Cardiff a week on Friday and then a trip to Paris on final weekend.

Wales have crossed for just two tries, both by wing Liam Williams, in the losses to England and the Scots and need to up their game considerably if they are to add to their opening day victory in Italy.

Howley has made no secret of his intention to play a more expansive game but things haven't gone to plan with a stodgy, if successful in terms of results, autumn before a wasteful Six Nations.

The management don't have a wealth of option at their disposal with uncapped wing Steff Evans a talent with ball in hand but a risk in defence but the case for Sam Davies at 10 is growing.

Biggar was superb against England, had no platform against the Scots and has been excellent in recent seasons at fly-half.

However, Guscott believes giving a new man a crack at 10 is an option given the paucity of flair elsewhere in the side.

"It's hard to change a big machine that Wales have been for so many years with the same players," said the former England and Lions centre on BBC Radio 5 Live.

"The only way that you can change that is if their skill set miraculously changes or you start putting the players with the requisite skill set to do what you want to do.

"That means changing the decision-makers, probably the 10. Dan Biggar for me is a world class player but he's not exceptional at releasing a back line and they don't seem to have any more ball-playing, passing guys there. They are pretty lumpy and pretty direct."

Paul Grayson, a World Cup winner with England in 2003, believes the return of Warren Gatland after the British and Irish Lions tour to New Zealand is hanging over Howley.

"With Warren Gatland away seconded to the Lions, it's almost like mum telling off the naughty kids and telling them 'wait until your dad gets home'," said the former fly-half. "It's waiting for Gatland to come back and rap them over the knuckles.

"It's almost like Rob Howley's not quite got the authority to say 'you, you and you, you're out and I'm going to go with these three kids because I think they're the future and this is what my team will be about'."
