LOOSEHEAD GARETH THOMAS believes a fast start is vital for Wales in their quest to claim an odds-defying victory over Guinness Six Nations title favourites Ireland on Saturday.

Wales have been largely written off, heading to Dublin after suffering nine defeats in their last 10 Six Nations games to face an Ireland side chasing successive Grand Slams.

Andy Farrell’s side have won 38 of their last 40 Tests at home, being beaten only by England during Joe Schmidt’s final year in charge and by France two years later during that time.

They are also closing in on a Six Nations record-equalling 11 successive wins, remaining undefeated since France toppled them two years ago.

And Wales must halt a poor recent Dublin record, having not landed a Six Nations win there there for 12 years when Leigh Halfpenny’s late penalty secured a 23-21 triumph.

“It is obviously going to be a challenge for us,” Wales prop Thomas said.

“But talking to the boys in the week and last week and saying how exciting it is if we get it right in terms of what we need to do. It’ll be a class challenge for us.

“It’s going to hurt, but it’s going to feel good if we get those bits right.

“I think starting fast, just going at them, not accepting their style of play, because if they get what they want they will be very good.

I think just going after them, going at them, beating them physically. If we don’t start like that, then we’ve no chance. They are playing some really good rugby at the minute, but watching the first two games (against France and Italy), people are letting them play like that.

“So it is up to us to go at them defensively and stop that smooth kind of attack they have got.”

Much has been made of a new-look Wales Six Nations squad, with Test rookies like Cameron Winnett and Alex Mann performing impressively during narrow defeats against Scotland and England.

Bath prop Archie Griffin joined them in making an international debut during the tournament, and 20-year-old Cardiff forward Mackenzie Martin will follow suit if he features off the bench this weekend.

And while Wales might no longer have the services of players like Halfpenny, Louis Rees-Zammit and Dan Biggar available – or, for the current Six Nations, injured trio Jac Morgan, Dewi Lake and Taulupe Faletau – green shoots are evident.

Thomas added: “We have lost a lot of senior boys, which is always difficult, but I am enjoying trying to help the younger boys who haven’t had that experience yet.

“We have got a group of young boys who are listening, learning and working really hard, so there is a good energy about the place.

“It is such a fine margin in terms of getting those two games to be wins (Wales lost to Scotland and England by a combined margin of three points).

“Give us those two wins, and we are in a very good place.

“The amount of effort that has gone into those first two games, we are going to need the same again, but close the game off a little bit better as well.”
