Warren Gatland believes that Wales' Guinness Six Nations opener against France is potentially their toughest assignment of this season's tournament.

Wales tackle Les Bleus in Paris on February 1 during a campaign that also sees them meet reigning Six Nations champions Ireland and Eddie Jones' England at the Principality Stadium.

And head coach Gatland is upbeat about his team's prospects following a first clean sweep of autumn Test wins that stretched Wales' unbeaten record to nine games.

I think we've got a great chance of winning the Six Nations, if we win that opening game. That first game is going to be our toughest. We feel like we are in as good a position as anybody to do well.
