Former Wales captain Sam Warburton says there is "no silver bullet" to Wales' problems and does not expect a change in coaching staff should they lose to Italy.

Warren Gatland's side suffered a 13th successive Test loss in their Six Nations opener to France on Friday.

Les Bleus ran in seven tries to inflict a record 43-0 tournament defeat for Wales in France.

Round two sees Wales head to Italy for a game that another former captain Dan Biggar described as the most important in Welsh rugby for 15-20 years.

Warburton says "I don't think it's their biggest game" with Wales playing for Grand Slam titles and in Rugby World Cup semi-finals during that period.

"I think what Dan meant was the consequences could be some of the biggest in the last 15 years," he told BBC Two's Six Nations Rugby Special.

"If they lose that game, they've then got Ireland, Scotland and England.

"It's tricky to see where the win is going to come, I think that's why people are pinning so much pressure on this game."

Whatever the result in Rome on Saturday, Warburton cannot foresee any changes to the coaching staff.

Gatland has been challenged by Welsh Rugby Union chief executive Abi Tierney to "lead Wales to success" at this year's tournament following an autumn review.

"If they lose this game I think there's going to be no changes made during the Six Nations from a staffing perspective," Warburton said.

"There's no silver bullet, everyone thinks they've got the answer.

"There is no coach in world rugby that is going to come in and make up a 43 point deficit.

"France didn't win a Six Nations for 10 years before they won their recent one, Ireland went seven years, but Wales is in a worse place."
