This weekend's plethora of European rugby action resumes with a couple of tasty tea-time tussles - La Rochelle v Leicester, and Leinster v Harlequins.

Saracens full-back Elliot Daly speaking to Premier Sports:

"We’ve started games well but we’ve not been consistent, we’ve let teams back in. That was the big message at half-time.

"To keep them to 10 points is testament to us but it's one game and hopefully we can go again next week against the Sharks.

"Having Max (Malins) back is brilliant, he understands the game so well. Noah (Caluori) gives us an edge in tight games. He is trying to learn every day and he’s doing really well."

Man-of-the-match Hugh Tizard, speaking to Premier Sports:

"We had a really good week building up to it against a physical Clermont side.

"We always say we decide who wins. We worked hard at the set-piece and to win games you have to have a dominant set-piece.

"It was good to get a try. We've had an up and down season but that's a good first step in Europe."

On the game against the Sharks next week:

"Going out to South Africa is always a challenge but we're looking forward to it.

A one-sided contest comes to an end with Saracens claiming a thoroughly deserved win.

They had four tries by half-time and added three more in the second half to brush aside a young Clermont team.

Job done for Sarries as they take a bonus point win in their opening match.

Clermont did score a couple of tries in the second half but never threatened to make it a contest.

Clermont have an attacking line-out.

They win it and go on the offensive.

Bautista Delguy is a talented wing but we've seen precious little of him today.

Full-back Axel Guillaud - who scored Clermont's try - has been one of their better performers. The teenager looks a good prospect.

There are a lot of young and inexperienced players out there for Clermont - including four teenagers - and they have given it their all but it has not been enough to unduly trouble Saracens.

Saracens number eight Tom Willis was on his knees when he moved the ball over the line so this one won't count.

Disappointment for Willis but it won't have much impact on the outcome.

Hollie Davidson thinks Sarries have another try - it's a bit of a mess on the ground.

We're just waiting for the verdict.

An hour on the clock and there's just a bit of a lull in the game as a number of subs are made.

Owen Farrell the latest to depart with Fergus Burke on for the final 20.

That's the end of Noah Caluori's afternoon - another fine try to add to the growing highlights reel.

Rotimi Segun is on in his place.

Clermont have also brought on four-cap All Black George Moala. He's since switched to play internationally for Tonga and has been at Clermont since 2018 making more than 100 appearances.

The familiar figure of Clermont coach Christophe Urios is on the sidelines and has seen enough to make five subs at once.

Experienced Aussie Rob Simmons is among the new faces - along with some rather more inexperienced youngsters.

Sarries scrum-half Ivan van Zyl makes a rare error from the restart as the second period gets started in rather chaotic fashion.

It's not long before the hosts have the ball back again but then as I type that Clermont get a penalty.

The ball is pumped into the Saracens 22 for a line-out.

Chance?
