Les Kiss says that Ulster must learn from their recent defeat to Munster if they hope to progress in the European Championship Cup.

Ulster are the only Irish province with a fighting chance of making the knock-out stages and they take on Oyonnax in Pool 1 on Sunday afternoon (kick-off 1.0).

The province’s director of rugby knows that they are favourites for this game, but warns that they need to do better than last weekend’s 9-7 defeat at home to struggling Munster at Kingspan Stadium

"The performance against Munster was not really up to the standards we expect and with some big games coming up we have got to look for solutions,” said Kiss.

"We have been very honest with ourselves as a group this season and that has been one of the things that has helped us get on the good run we have been on.

"We did not over-react when we lost games before and we need to show that same attitude now, to look over things in a pragmatic fashion, grow from this defeat and learn the lessons before we face Oyonnax."

Ulster are second in the group, nine points behind leader Saracens, though they have a game in hand.

Oyonnax are bottom of the table with three defeats from three.This match was postponed late last year in the wake of the terror attacks in Paris in which more than 100 people died.

Leinster are bottom of Pool 5 with two points while Munster are second bottom, having only managed to beat Treviso so far.

Ireland winger Craig Gilroy returns for this game and he will start at full-back for Ulster.
