Munster's famed red army have travelled in their numbers again for this one.

It's been like a carnival around the Vieux Port all day with Munster chants starting early in the morning and fans soaking up the sunshine on France's Atlantic coast.

There's red jerseys (and more than a few red berets) everywhere you look and it should make for a cracking atmosphere come kick off at the Stade Marcel-Deflandre

Munster have enjoyed some great days in France, with plenty of them involving the man in the opposing coaching box today, of course.

Will we see an other today?

Thanks Mantej! Good stuff!

We've had two very one-sided matches so far this afternoon but I have a feeling this one will be that bit closer.

Munster legend Ronan O'Gara will lead La Rochelle against his former side in France, and we'll have live updates right here.

It should be a good one!

From one Irish province to another, it's time then to look ahead to Munster's trip to La Rochelle.

My colleague Andy Gray will build-up to that one next...

Speaking to Premier Sports, player of the match Josh van der Flier, said: "It was a brilliant performance from the lads, a lot of them stood up.

"It was huge keeping Harlequins out in the first 20 minutes and the scoreboard probably doesn't reflect how good a side they are.

"[Croke Park] is a very cool place to play. Everyone in Ireland knows what a special place this is, so it is always a pleasure.

"It is hard to peak at this time of the year but we have a lot of important stuff left so hopefully we can keep this performance level up as a team."

Im seriously impressed. You would be intimated watching that because you wouldn't want to come up against this Leinster team in Ireland.

Ross Byrne's conversion is the final act.

Leinster have thumped Harlequins, who didn't land a shot.

Leinster are throwing passes without thinking because they have drilled it so hard. They are passing into space.

They just continue to keep the ball alive and score in the corner. They are such a well drilled and well coached team.

Jamie Benson joins Luke Northmore in the bin for a tap-tackle on Jordie Barrett before he had received the ball.

I think Quins would be happy if the final whistle sounded now.

They're down to 13 now.

The level this Leinster team is at is outstanding. Brilliant tap tackle to stop that being a try in the first instance. Leinster players flooded the space.

Luke Northmore can have little complaints as he is sent to the bin for his deliberate knock-on.

Quins down to 14 for the next 10 minutes.

Welcome to Dublin, Danny Care.

The diminutive scrum-half is double-teamed in a thumping hit by a couple of front row heavyweights in Gus McCarthy and Tadhg Furlong.

The Quins nine sees the funny side as he gets back to his feet with a beaming grin on his face.

Luke McGrath evades a couple of attempted tackles but his audacious offload goes forward and the chance disappears.

Leinster are trying a few party tricks now with the result seemingly assured.

It's just too easy. The jumper lands and the maul is set. It's the same two faces every time against Danny Care set waiting at the back.

Skills.

Sam Prendergast lands his kick on a sixpence as it bounces just before going into touch, inches short of the try line.

The Leinster faithful certainly enjoy that one.

To compound matters for Quins, Leinster have just introduced New Zealand's Jordie Barrett off the bench.

Not a terrible option to chuck on.
