Saracens will take on French giants ASM Clermont Auvergne at Vicarage Road in the Heineken Cup quarter-finals on Sunday determined to make up for losing their domestic battle with Harlequins.
Sarries were beaten 24-19 by Amlin Challenge Cup holders Quins at Wembley Stadium on Saturday afternoon and director of rugby Mark McCall admits they have plenty of work to do before next weekend.
"We have a massive game against Clermont, a team in hot form in the Top 14 and a truly outstanding squad," said McCall.
"They are a very good team and we will really have to perform on the day. We'll need to make sure we are a lot more clinical because against Harlequins we were given a bit of a lesson in finishing, although the main reason we lost was because physically they were better than us."
The pre-match entertainment produced a carnival atmosphere at the home of English football before the rugby took centre stage with a full-blooded contest high on intensity and no shortage of quality.
And it took Amlin Challenge Cup quarter-finalists Harlequins less than three minutes to get the first score, centre Jordan Turner-Hall crossing before co-centre George Lowe added a second after 23 minutes.
That was a superb solo effort with All Blacks outside half Nick Evans adding both conversions.
But Harlequins will kick themselves for gifting Saracens points through indiscipline, England outside half Owen Farrell - playing in the centre for his club - landing four of the five penalty goal chances on offer, his one miss from long range dipping just below the crossbar.
Scrum half Danny Care got Quins' third try midway through the second half, replacement Rory Clegg adding five points with the boot, but it was Harlequins' fantastic scramble defence that kept Saracens out on more than one occasion when a try looked on the cards.
But with first Joe Marler, then Care and finally Nick Easter being shown yellow and sent to the sin bin, reducing Quins to 13 for a couple of minutes on each occasion, their discipline was letting them down.
And while men short Richard Wigglesworth belatedly got Saracens' first try, Farrell converting, only for it to be too little too late for the "home" side.
The directors of ERC voted unanimously at a Board meeting to postpone all decisions including the release of further instalments of ERC's distributable central revenues to the six shareholder countries until 19 February next when the Board will meet again to reconsider the issue.
