Harlequins 0-7 Saracens
Saracens out of the traps with some intent and some quick ball! It's an opening try of the game from Brad Barritt.
Harlequins startled there as Owen Farrell was heavily involved with quick handling. Vincent Koch then found the running line through the home defence and Barritt did the rest from close range after being fed by Jamie George.
Farrell adds the conversion off the inside of the post.

Right - that's the build-up all out of the way. Now it's the players' turn to help write the rest of this script.
Both teams are out of the tunnel and it looks like a full house at The Stoop for this one.

Has Exeter's clinical victory against Bath yesterday shown they're the team everyone else needs to catch?
Are London Irish already in too much trouble at the bottom to escape an immediate return to the Championship?

Saracens come into this trip to The Stoop with work to do if they are to catch up with leaders Exeter.
The Chiefs edged-out Sarries 20-18 at Allianz Park last Sunday, a win today for Mark McCall's men could potentially bring them to within five points of the top.
Image source, .Quins have struggled for consistency this season so far, but the top six European Champions Cups spots are far from out of reach at this stage.
Victory for the hosts would see them climb to seventh.

Gloucester moved up to second after inflicting a ninth league defeat on London Irish at Kingsholm and Wasps closed the gap to the top four to one point with a narrow 32-25 win at home to Leicester.
On Friday evening, Sale and Newcastle moved into mid-table with narrow away wins at Worcester and Northampton respectively.

Harlequins v Saracens (15:00 GMT)
Image source, Getty ImagesHarlequins club captain, Australian James Horwill, will no doubt have liked the look of the cricket score this morning in the second Ashes Test in Adelaide.
He'll also appreciate the cricketing analogy I've used to recognise his 50th appearance for the club this afternoon.
Can the tall second row lead his side to a big win on home turf this afternoon to make his landmark appearance even more memorable?

Sunday derby feastpublished at 19:23 Greenwich Mean Time 1 December 2017
Harlequins v Saracens (15:00 GMT)
Premiership action never fails to deliver and this Sunday afternoon we've got a real treat for you to finish off round 10.
We're at The Stoop for the London derby between Harlequins and Saracens.
The home mascot's already excited and I'm not sure I can contain my excitement that much either.
A host of internationals are back in club colours after the Autumn series and both sides are desperate for a win for very different reasons.
Kick-off is 15:00 GMT and team news is on the way very shortly....
