NEWPORT Gwent Dragons tyro Hallam Amos has been urged to dazzle of the bench to cement a place in Wales' World Cup squad, writes Chris Kirwan.

The 20-year-old wing/full-back is set to win his third cap when Warren Gatland's team take on the Six Nations champions in Dublin tomorrow (kick-off 2.30pm).

The big guns are back for the clash at the Aviva Stadium but opportunity knocks for a handful of players. Gatland names his 31-strong squad for England 2015 on Monday and revealed earlier this week that he has already pencilled in "25 or 26" players.

Dual-contracted Amos, who started against the Irish at the Millennium Stadium at the start of the month, looks set to get the nod but an impressive cameo would see the Dragons speedster, who has impressed the Wales management with his pace and power, inked in.

"We are looking for more of the same from Hallam," said skills coach Neil Jenkins. "He is a very good rugby player and did pretty well in his outing earlier this month.

"We know how good he is. He is a fantastic all-round rugby player who shows off his skills with the Dragons and has always impressed us in camp.

"We want him to enjoy himself today and show off his skills. He is an incredibly talented young player who will have a bright future with Wales, and hopefully in the coming weeks at the World Cup."

Amos started at full-back for the first time in almost a year in the Cardiff clash before moving to the wing. An outing out wide looks likely to allow George North to have a run out in midfield this afternoon.

"There are some out-and-out wingers but an awful lot can play in more than one position," said Jenkins.

"Look at Keith Earls with Ireland – he can play centre, wing and full-back. Maybe in the long term Hallam could do that, he's that good.

"In World Cups you need people who can play in different positions and Hallam fits that bill."

Wales' second string were thrashed 35-21 by the Irish in Cardiff but Jenkins expects a closer affair at the Aviva with big hitters such as Alun Wyn Jones, Jamie Roberts, Gethin Jenkins and Leigh Halfpenny chomping at the bit.

"It's the first game of the season for most of them and it can't come quick enough," said the former fly-half.

"It's a big test for us – Ireland are playing exceptionally well and have a fantastic record in Dublin over the last couple of years.

"You can feel that by the way that we have trained this week and we are looking for a very good performance.

"Ireland are a very good, skilful, uncompromising side who play the game intelligently. We know what to expect and it's going to be tough."
