Romain Ntamack is not far from grabbing an intercept there.

The Toulouse fly-half fumbles forward though as he flies up.

Maybe that is about sowing the seed of doubt in the Exeter backline, making them think twice before giving the pass...

Toulouse are trying to play from deep inside their own 22m.

Ambitious stuff against Exeter's famed defence.

They don't get caught out, but can't find a hole either.

The visitors eventually resort to Thomas Ramos' boot to clear their lines.

Henry Slade, with the penalty advantage in his back pocket, throws a big mis-pass to find Jack Nowell out wide.

Nowell can't get over the gain line and we will come back for the kick.

Joe Simmonds takes play deep into the Toulouse 22m...

A lovely little snipe and shift from Antoine Dupont as he feeds Selevasio Tolofua. On to more heavy-duty carriers in Joe Tekori and Rory Arnold.

Exeter infringe. Penalty red. And Thomas Ramos steps up to pot it over...

Toulouse have started at break-neck speed...

Cheslin Kolbe has a dart down the wing. Exeter's defence has double bagged against the danger man and shuts the door.

But Kolbe slings an offload back from the brink of the touchline...

Toulouse are running through the phases, stretching the Exeter defence this way and that around halfway...

Warren Gatland and Eddie Jones, Lions and England coaches respectively, are in the empty stands. We are up and under way as Joe Simmonds drops out...

"Toulouse have players who have scored straight from nothing. The likes of Cheslin Kolbe and Antoine Dupont attack instinctively, reading the space so well.

"Defensively that is nigh on impossible to prepare for.

"Exeter are a very different team, very structured. You know what is going to happen. You just have to try to somehow stop it."

From the thumping music and blinding lights of La Defense Arena to a sparkling, chill day in Devon.

Next up in this Anglo-French double header is Toulouse's visit to the south west and the in-form Exeter Chiefs...

The big screen at the La Defense Arena launches into a strobe-heavy celebration graphic.

The Saracens players drop to their knees, their team is heading to the Championship, their stars are being scattered, the future for everyone concerned is unclear.

Sean Maitland is bundled into touch.

Saracens raging against the dying of the light is finally over...

Racing think they have won it as Nigel Owens blows.

But the referee wants the scrum reset.

It is not over yet. But the fat lady has taken the stage....

Racing claim the line-out clean though Boris Palu and the ball is tied in tightly to run down the clock...

Hang on.

Maxime Machenaud fumbles at the back of the maul and Saracens have put in to a scrum just outside their own 22m.

The clock is red. They have to go the length...

That might be the ball game.

Elliot Daly is penalised for a nibble too many at the breakdown.

Racing penalty on the Saracens 10m line. Finn Russell opts to kick into the corner and wear down the clock...

It is like a fairytale. Racing have been nowhere close to scoring a try. But what have we said in the opening 76 minutes, it's a moment of brilliance from this backline.

It was a beautiful chip from Finn Russell.

Racing with possesion just short of halfway.

Saracens strung out wide in defence...

Penalty to Saracens as the Racing front row drop to their knees!

At last, an easy out for the defending champions after vice-like pressure.
