Howley, who will take charge of Wales in a caretaker role against Argentina and Samoa before Warren Gatland returns for the clashes with New Zealand and Australia, has named an initial 34-man squad. 

Sam Warburton remains as skipper with the fit-again Roberts and the impressive Biggar also recalled to a squad that struggled in their summer tour to Australia but swept all before them in this year’s RBS 6 Nations.

France-based players Gethin Jenkins, James Hook, Mike Phillips and Luke Charteris are all included but there is no place for Clermont full-back Lee Byrne.

And Howley insists that his squad is more than capable of turning a few heads this autumn as they bid to overhaul England and France in the IRB World Rankings to become a top seed ahead of the draw for the Rugby World Cup in 2015.

“We are really pleased with the strength and depth of the squad with some pleasing individual performances over the last three or four weeks,” said Howley.

“This is one of the reasons we are going back to our training camp in Poland to sharpen minds and bodies.

“Argentina are first up and after the experience they have gained in the Rugby Championship they will be a challenging and tough opponent, but this is a challenge we will look forward too.

“We know how important momentum is going into any series and the bigger picture is the Rugby World Cup draw at the beginning of December.

“How we perform against the Pumas, Samoa, the All Blacks and the Wallabies will have a direct effect on our seeding in that draw.

“We need a successful November to back up our performances at the RWC in New Zealand and the Six Nations Grand Slam earlier this year and we are determined to achieve it.”
