HEAD coach Rory Duncan is set to back his history boys to repeat their European Challenge Cup heroics when a “strong” Ospreys side arrive at Sixways on Saturday (3pm).

Worcester Warriors fielded an entirely new starting 15 for their opening Pool Two clash against second-placed Top 14 outfit Stade Francais in Paris last Saturday.

And Worcester showed their strength in depth as a Tom Howe brace and tries from Matt Cox, Ted Hill and Jamie Shillcock secured the visitors a historic 38-27 victory.

It was Warriors’ first win in France in a decade and their highest score on French soil, beating the 31 they scored at Montpellier in the 2005-06 campaign.

Warriors’ Premiership regulars including Bryce Heem, Francois Hougaard and Duncan Weir have returned to training this week.

But Duncan said he was “pretty sure a lot of the guys” that featured in the team who stunned Stade Francais would get another chance to shine.

“There is quality throughout the squad,” Duncan said.

“I think a lot of those players (that played in Paris) had a point to prove.

“All the players are in this week so we have got make a call as a coaching group how we want to manage this game.

“Obviously selection is going to be difficult as we have got a number of guys that put up their hand last weekend and showed that they have the ability to do the job in hand.”

While Warriors rung the changes, Ospreys stuck with largely the same side that lost 20-17 at Scarlets in the Pro14 for their European opener against Pau.

The likes of experienced Wales stars George North, Justin Tipuric and James Hook steered the region to a 27-0 victory at the Liberty Stadium.

And Duncan expects Ospreys to put out a similar team when they tackle Warriors.

“I anticipate that they will put out a strong side,” Duncan said.

“Ospreys are a team that play with a bit of tempo and great line speed.

“They have certainly done a lot better in the Pro14 than last season as they are sitting second in their pool so it is going to be a tough game.”

Duncan was thrilled with his players’ performance against Stade Francais but insisted they were aware there was plenty of room for improvement.

“I think the guys have put the win behind them now and are focusing on the game ahead,” Duncan said.

“It has not been difficult to keep their feet on the ground.

“By the time we came in and did the review the guys realised that there was still more to come.

“It is about fulfilling our potential and that means trying to string as many 80-minute performances together as possible.

“The guys have worked hard so I think there are in the right frame of mind.”
