SCRUM-HALF Jonny Arr urged his Worcester Warriors team-mates not to spurn their chance to secure a quarter-final spot ahead of Saturday’s European Challenge Cup showdown at Ospreys (3pm).

It has been a decade since Worcester last progressed beyond the pool stages after reaching the final in 2008 and semi-final in 2009.

Arr, 30, played a part in both memorable cup runs and is determined to reach those heady heights again.

With two matches left Warriors hold a two-point lead over Ospreys at the top of Pool Two with 13 points from their first four games.

Five group winners bag a place in the final eight along with three best runners-up.

“In my first season here we got to the final so it has been a while since we got there,” Arr said.

“It would be a shame to put ourselves in the position we are in and not to follow it through and gain qualification.

“But it is going to be a tough task with Ospreys away from home which is going to take a huge effort and then Stade Francais who are one of the biggest clubs in the world coming to Sixways.

“They are two tough games. But if we could qualify then it would be a really good moment for the club and certainly be up there with my best moments.

“You want to play in big games and going through to the knockout stages of a European competition will present that. That’s what we all want to be a part of.”

First-half tries from Jamie Shillcock, Wynand Olivier and Jack Singleton saw Warriors overcome Ospreys 27-21 at Sixways in October.

But the Welsh region have won eight of their nine games at the Liberty Stadium this season and will be keen to boost their own qualification hopes.

“The boys have made a really good start in this competition,” Arr said.

“Going to Paris and getting that first win was massive and then backing it up the week after against Ospreys.

“Moving forward we got a victory in nasty conditions against Pau which has put us in a good position. We go into this match aiming to keep the momentum.

“Ospreys have got a quality side with good strength in depth as well so we have got a difficult task ahead of us.

“It will take a big effort to go and get a victory. But the boys have proven before that they can go on the road and win big games so we will try to do the same.”
