After resigning in 2006 and, after a short spell in charge of Worcester Warriors, Ruddock took the Irish Under-20 reins from Allen Clarke.

But in his first match against his homeland, Ruddock has promised Ireland supporters he won’t let his heart rule his head.

“I can’t wait for the Wales game, I’m looking forward to it,” said Ruddock.

“It’ll be an interesting game for me personally, and there will absolutely be divided loyalties.

“I’ve asked the Irish RFU for permission to sing both anthems, because even though my mother is Irish and I have an Irish passport, I’ve lived and coached in Wales so it’s only right that I show my respect to both countries.

“Ultimately of course I hope Ireland U20s come out on top.”

Ruddock makes just two changes from the team that defeated Scotland 15-0 with centre Luke Marshall and wing Craig Gilroy returning from Magners League duty with Ulster.

They replace JJ Hanrahan and Tiernan O’Halloran, who both drop to the bench and Ruddock concedes Wales will offer a far greater challenge to his team.

He said: “It’s great to have guys like Paddy Jackson and Luke Marshall back with us from Magners League duty, because they’re talented boys and they bring that experience, knowledge and confidence back with them.

“Wales play some great rugby; even with 14 men they still put 40pts on Italy. If we give them time and space, they’ll move the ball, in that traditional Welsh way.

“We saw a big improvement in our defence against Scotland, particularly in terms of our line speed and in the collision, which we dominated, so we hope to take that into the Wales game.”
