Former England fly-half Paul Grayson: "You need a little bit of luck and earlier it was harder not to score than score for Racing Metro. Saracens are playing some smart stuff."
Johnny Sexton sniffs a half-gap on the Saracens' 10m, and swerves inside. Jackson Wray is across superbly to take him to the floor though. And regain possession.
Richard Wigglesworth puts boot to ball and ease the pressure on Sarries. The visitors are under the cosh though.
They are definitely over.
But I think the Racing man in the middle of the rolling maul dropped the ball as he grounded under pressure from Jackson Wray...
Nigel Owens agrees and it is a scrum five for Saracens. Lots of Gallic shrugging and gesturing up in the Racing coaches' box.
Pressure on Saracens now though. Line-out for Metro just 10 metres out and it is safely claimed by the hosts....
Saracens' defensive line is coming flying up as if they haven't tasted meat all week.
They do enough, getting big in the face of Brice Dulin and ensuring that his patted flick-on drifts forwards on its way towards Teddy Thomas.

Former England fly-half Paul Grayson: "Nigel Owens is an experienced official and he used the TMO. Teddy Thomas is a very powerful athlete and fell over far too easily after that collision."
Racings fans are whistling and jeering like only a Parisian crowd can.
Winger Teddy Thomas chipped over the top and seemed to be blocked off from chasing his own kick into the end zone by Alex Goode.
Goode was subtle enough though, turning his back and popping his hands up apologetically as he body-checked his man to escape punishment from Nigel Owens.
Streetwise stuff and it relieves some pressure on Saracens.
Metro number eight Antonie Claassen makes yards as the hosts rumble ominously.
But their momentum is checked as Nigel Owens spots one of his team-mates failing to join the back of a ruck.
Saracens have put some grunt into that. A very promising set-piece ends with the visitors going forwards, Metro prop Luc Ducalcon popped out of his bind and referee Nigel Owens with no choice.
He blows up for an obvious penalty and Charlie Hodgson ignores the jeers to slot from 35 metres-ish.
Oh! A little bit of joue from the French.
Johnny Sexton chips over the top of the Saracens defensive line from inside his own 22m line.
That champagne is corked though. An over-cooked kick is gobbled up by Alex Goode, before Metro centres Jamie Roberts and Henry Chavancy can put any real pressure on the catch.

Former England fly-half Paul Grayson: "Saracens are coming back to form but they need to be neat and tidy and stay away from the set-piece. This is a small ground but Racing Metro have wads of cash and have packed their side with internationals. This is almost like a military operation for Saracens."
"If you don't understand me, what chance have they got?" Referee Nigel Owens pokes fun at thick-eared Charlie Hodgson before the Sarries fly-half boots long.
Brice Dulin gathers safely and Johnny Sexton takes play back up to halfway with a thumper of a kick. Billy Vunipola lost the flight of it in the low sun and had to abort his attempt to catch on the touchline...
Andrew Priestley:, external Tough day for the English sides yesterday. Saracens are the best hope today, but Racing Metro can be unstoppable on their day.
Right, after a minute's applause for two late Racing stalwarts, time to get this one under way...
Out come the teams.
Dimitri Szarzewski sprints out at the front of the Racing queue.
Saracens' Richard Wigglesworth comes over all David Sole in 1990 and goes for a slow trudge.
Nigel Owens has got the whistle for this one.
"Rac-ing! Rac-ing! Rac-ing!"
The home crowd, with a little encouragement from a motor-mouth PA, get the vocal cords warmed up.
They have not seen their side beaten on home turf for five months.
Champions Cup:, external Johnny Sexton has never lost a knockout European Rugby game.
Saracens director of rugby Mark McCall to BT Sport: "We have got some momentum going into this tie but today is a different kettle of fish. Intensity levels and physicality will go through the roof. People know there are not too many areas to exploit in this Racing Metro side. They have got some huge men to carry the ball."
Saracens have retreated back into away dressing room for their final instructions from coach Mark McCall.
I think an estate agent would describe Stade Yves du Manoir as "cosy, with development potential".
It is more than a little dog-eared round the edges and a world away from the shiny Allianz Park that Saracens call home.
Racing's headquarters was also used to film scenes for the film Escape to Victory though. Sylvester Stallone and Pele are yet to make an appearance in Barnet.
While the atmosphere ramps up in the Stade Yves Du Manoir, over at Stade Mayol the scene is set for defending champions Toulon's meeting with Wasps.
Live coverage of that one follows hot on the heels of Racing Metro v Saracens...
