Howley has faith in youth
Rob Howley expects "a highly-motivated" Wales team to take the field in Saturday's farewell game before tackling Australia Down Under.
Howley, in temporary charge while Wales supremo Warren Gatland recovers from two fractured heels at his New Zealand home, will parade three new caps against Millennium Stadium visitors the Barbarians.
Scarlets full-back Liam Williams and prop Rhodri Jones are both handed first Test match appearances, together with Cardiff Blues wing Harry Robinson.
The trio have a combined age of just 60, only 24 years older than flanker Martyn Williams, who is among Wales' replacements and set to win his 100th cap, joining Welsh centurions Stephen Jones and Gareth Thomas.
Welsh rugby's current feelgood factor, generated by winning this season's RBS 6 Nations title with a Grand Slam just five months after reaching the World Cup semi-finals, is supported by an anticipated crowd of around 50,000.
"When you've won the Grand Slam and been in a World Cup semi-final, it would be pretty ridiculous to change things," Howley said.
"It is business as normal, really. We feel that we have a squad that has been together for a long period of time and has the appetite to wear that national jersey.
"It has been interesting in terms of the dynamic of selecting the side for this game in terms of selecting on reward, on building depth and looking at fresh talent.
"I think all those ingredients are in the team on Saturday, and all the guys will be highly-motivated."
A 16-strong group of players, including uncapped Ospreys centre Ashley Beck, are set to leave for Australia tomorrow with assistant coach and defence specialist Shaun Edwards.
That list, which also includes star names such as Sam Warburton, Mike Phillips, George North, Adam Jones, Dan Lydiate and Toby Faletau, will step up preparations for the first Test in Brisbane on June 9
The remaining 18 tour squad members then arrive Down Under early next week, with Howley intending to finalise names after Saturday's Baa-baas encounter.
"We have picked a side on form, with an eye on bringing players through for the future, but very much with the intention of getting the summer campaign off to a winning start," he added.
"We have an opportunity against the Barbarians to get an important summer series off to a winning start.
"We have momentum from the Six Nations, and the Ospreys have added to that with a great (title) win last weekend in our domestic competition.
"We are now looking for the next step and a victory on home soil against the Barbarians before we set off for Australia."
Scarlets hooker Matthew Rees will captain a Wales team that includes a number of fellow Grand Slam and Six Nations winners this season such as locks Alun-Wyn Jones and Ian Evans, plus number eight Ryan Jones.
And there are returns to the Test arena for Ospreys centre Andrew Bishop and fly-half Dan Biggar, who both played key roles in last Sunday's RaboDirect PRO12 title-clinching victory over European champions Leinster in Dublin.
Williams apart, the bench also includes uncapped 21-year-old Scarlets centre Adam Warren and three more Ospreys in hooker Richard Hibbard, prop Paul James and scrum-half Rhys Webb.
"The Barbarians will be coming to play a lot of rugby," Howley said.
"Possibly, with the likes of Shane Williams, Isa Nacewa and Mils Muliaina in their back-three, it just shows the attacking intent and quality of player they have."
Shane Williams, Wales' record Test try-scorer, makes his final appearance before retirement fresh from a two-try Ospreys farewell in Dublin, while Howley will send Martyn Williams on at some stage of the second period.
But despite two greats of Welsh rugby bowing out this weekend, Wales know that nostalgia and sentiment cannot blur the need for a strong display.
"We've got a big four weeks ahead of us," Rees said.
"So it is important we start off with a good performance and result on Saturday."
