Six Nations 2015: Dropping Alex Cuthbert may do him good - Martyn Williams

Alex Cuthbert has scored 14 tries in 31 starts for Wales

Dropping Alex Cuthbert for Wales' Six Nations game against France may do the winger good according to his former Blues team-mate Martyn Williams.

Cuthbert, 24, is to be spoken to by the Welsh management after a video emerged of him appearing to throw a mobile phone belonging to a member of the public down a street.

Williams says a rest may do him good.

"Pulling Cuthy out of the firing line would do him no harm whatsoever," said Williams.

Cuthbert has not scored in his last four matches for Wales and his last try was against Fiji in November 2014.

He averages just under one try every two games for Warren Gatland's side, and with George North likely to return and the emergence of in-form Liam Williams, Cuthbert's place looks in doubt.

"He's a great player. For three years he has done nothing but play at the top level," former British and Irish Lions back row Williams added.

"As much as it would hurt to be dropped, it makes you as a player."

Williams, who played with Cuthbert for Wales and Cardiff Blues, also believes second row Luke Charteris could get the nod over Jake Ball to start against the French on Saturday, 28 February.

Charteris has yet to start for Wales in the tournament, but did impress off the bench in the Scotland win.

The former Wales flanker says the lock, who plays his club rugby in France for Racing Metro, could help nullify the threat posed by France's pack.

"France will drive line-outs and one of the best guys at stopping driving line-outs is Luke Charteris," said Williams.

"He's got arms like Inspector Gadget reaching around and he's just a nuisance."

Wales attack coach Rob Howley said Charteris stood out against Scotland.

"I think he was very impressive when he came on," said Howley.

"I thought that there was a great impact off the bench on the weekend and there certainly was an increased intensity.

"Obviously Luke is a very effective player at stopping driving line-outs and there seemed to be a change in momentum when our bench came on.

"We've always spoken about 23 players. It's a squad and the impact from our bench is critical."
