Warren Gatland believes Wales can win the Rugby World Cup in Japan if they continue to 'play as well as they have for the last year'.
Wales thumped Ireland at the Principality Stadium on Saturday to be crowned Grand Slam champions - their first Six Nations title since 2013 - and their recent run of good form has seen them climb above Joe Schmidt's side to second in the world rankings.
The five successive victories in the Six Nations extended their winning run to 14 matches and Gatland is feeling confident ahead of the World Cup later this year.
"I promise you that these guys will give 100 per cent in every game at the World Cup and, if we play as well as we have for the last year, then we can bring home the World Cup," Gatland told supporters at a ceremony to celebrate their Six Nations triumph.
"We've got a very special group of players at the moment. We enjoy each other's company, we challenge each other on a lot of things, but once we make a decision, we back each other 100 per cent."
Wales are in Pool D along with Australia, Georgia, Fiji and Uruguay and Gatland, who will leave his position as head coach after the World Cup, has vowed his squad will be in the best shape possible heading to Japan.
"You need a little bit of luck and hopefully we don't pick up too many injuries," Gatland added.
"We'll have a few months preparation and, as we have in the last few World Cups, we'll be one of the fittest teams, if not the fittest, there."
