Premiership leaders Harlequins will host Munster in the Heineken Cup last eight after qualifying as top seeds.

Director of rugby Conor O'Shea's men beat Biarritz 16-9 thanks to a Tom Guest try from close range and 11 points from fly half Nick Evans, who was named man of the match.

Quins will travel to either Clermont Auvergne or Montpellier should they reach the semi-finals, which are played on April 26-28.

"Munster is one of the great teams that have set the standard that all others aspire to in the Heineken Cup," said O'Shea.

"The province has vast experience in the tournament having reached the knock-out stages on numerous occasions and they are previous champions.

"They will bring that pedigree and their great rugby-playing tradition to the Stoop.

"They will also bring great support so Harlequins and its supporters are assured of a truly memorable occasion.

"All of that is two months away, in the meantime we have much rugby to play in the Aviva Premiership and LV= Cup and that starts with this weekend's match with London Welsh."
