Racing Metro have not been able to build any concerted pressure since cutting the gap to one point.

A lot of that has been due to some canny play from Saracens, who have booted the ball long and well to keep play in the French side's half and tackled hard to prevent it coming back.

Neil de Kock on for Richard Wigglesworth for the final 15 minutes at scrum-half for Saracens. The dynamic Maro Itoje has also been summoned into the fray for the visitors.

Alex Goode, skipping like a young foal, bounds between a mob of Metro shirts and into the fresh air. A lovely slicing break but it is a little too good for his own team-mates and a lack of support means the danger dies away.

Former England fly-half Paul Grayson: "That was a wobbly old kick but the wind did its trick and it's worth three points. Saracens are hanging on. Saracens need to get the ball back. They have spent the last 15 minutes in their own half but they've only conceded three points."

Suffocatingly tight now.

Just the one point in it as Maxine Machenaud makes good on a kick from just outside the 22m.

Twenty minutes to find a winner in amongst all this. This is what all the bleep tests and hours in the gym are for.

Overthrow! Saracens clean up the scraps at the back to regain possession. They were in a tight little corner there and that was a welcome mistake from Metro replacement Julien Brugnaut.

Referee Nigel Owens blasts his whistle to stop play. Good attentive officiating as well because Metro winger Juan Imhoff was out cold after copping a knee to the head from team-mate Johnny Sexton.

Imhoff heads off for a battery of tests as play restarts in the Saracens' half. And Metro have a line-out 10 metres short...

Some tremendous defensive work from Billy Vunipola as he bridges across the tackled man and refuses to budge under heavy fire, earning the turnover for Saracens.

Saracens look like they have been cut to ribbons as Brice Dulin skips past Jim Hamilton on half-way and canters into space.

Some tremendous covering tackling from Charlie Hodsgon and Marcelo Bosch just about stem the bleeding in time though, forcing the knock-on and giving Saracens a scrum on their own 5m line.

By the way Jamie Roberts is off and former Northampton prop Brian Mujati is on as part of a raft of Metro changes. Schalk Brits is back after six months out for Saracens, replacing Jamie George at hooker.

Saracens squander a good position after that knock-on by Brice Dulin. Billy Vunipola's offload is a bit of a bullet and Richard Wigglesworth cannot take it into the breadbasket.

Former England fly-half Paul Grayson: "One thing for certain is that Saracens need more points, they need to score again. But the longer this goes on the more Racing are going to have to force the game."

Mistakes are now pockmarking Racing Metro's play.

Johnny Sexton clumps the restart long, long and dead, before Brice Dulin spills forward as he attempts to claim the mark inside his own 22m.

The French bigspenders' cohesion and commitment is coming under the microscope now with some of the crowd having a grumble and groan.

As Charlie Hodgson takes a moment to catch his breath, Alex Goode steps up to the kicking duties. He catches it clean as a whistle and Saracens's lead inches out to four.

Rip the tackling page out of the textbook. Wenceslas Lauret has just provided an update - chopping down Charlie Hodgson around the thighs, but Saracens have a penalty....

Andrew Priestley:, external Saracens might rue those missed Charlie Hodgson penalties in the first half. Would a certain Owen Farrell have missed those kicks?

Racing Metro have a decent wrecking squad at work in the line-out. Saracens try to march a rolling maul on from the half-way line, but they are prised apart by some powerful Metro drivers.

I haven't seen that in a while. Johnny Sexton's kick-off is a little heavy, Marcelo Bosch claims under no pressure and pops it to David Strettle outside him who very nearly gets outside the chase and into the guts of the Metro half.

Just a stud into touch prevents Saracens applying some huge and early pressure...

Saracens huddle up in their dressing room as Mark McCall issues his final orders.

Then it is back out into the Paris spring air for the second half...

Meanwhile down south there is plenty of support for Wasps ahead of their game against Toulon.

A pocket of yellow on the Mediterranean coast. Still I'm sure it doesn't beat Coventry.
