There were a number of useful individual efforts against Ireland, but Wales were second collectively, and Cunningham rewarded the efforts of those who came off the bench last Friday.
“It’s an opportunity to give the players a chance plus we also felt the players who came off the bench against Ireland made an impact so they got a chance to get the starting shirt,” he said.
“With the nature of the competition, it’s a chance to rev things up and give players who don’t have several minutes on their legs to start – I hope they’ve got more energy and can start the game well and can sit on the bench and finish it.”

A number of players got their hands on training and Cunningham was keen to give them a chance to shine.
“Players like Olly Burrows, James Fender, Crest Chiunza and Will Reed have been very good in the environment, helped the team prepare and deserve this opportunity to get their start shirt,” he said.
Tshiunza is known as The Lock, but Cunningham has no qualms about playing with him on the blind side because he believes he has the skills to handle him.
“We’re playing with him in six because we want to put him on the field and we want to have a good squad so with David Jenkins, James Fender and Crist he gives us a good squad and there are some good athletes out there.
” Jesus is very athletic, so he can cover sixth place and it’s a chance for him to really move from the first minute.”
The Welsh camp remains optimistic, despite the Irish setback.
“This is a great competition to develop and learn right now, we are seeing guys develop fast and learn fast, and hopefully it will come out in the years to come,” Cunningham said.
“They will be the future of Wales rugby in four or five years.
“I spoke to the Irish coaches after the game and they said they are a year older in all areas.
“Give it a year and we’ll have a very good squad with a number of these players coming back next year.”
