Hmm, cancel that last comment. Franco Smith won't be happy at all after Leinster's first attack of note ends up in a try for Jack Boyle.

We told you about him before kick-off. An Irish Test player in the making. Looks a terrific prospect at the tender age of 21.

Kyle Steyn runs a great line and takes his side up to the Leinster 22.

The Warriors want an immediate response.

Leinster might not have threatened with ball in hand this far Tom, but they are into the Glasgow 22 here.

Big defensive set needed for the hosts.

Glasgow doing their best to warm-up a fairly subdued home crowd. Tough audience.

Warriors playing with a lot of ambition. Two excellent tries that had mighty work from back-row forwards (Rory Darge and Gregor Brown) at the heart of them.

Leinster haven't threatened with ball in hand at all. Franco Smith is hard to please but he should be happy enough so far.

The grounding is fine, and the try is confirmed to the delight of the home crowd.

Tom Jordan's conversion attempt from the touchline is dragged wide.

Through it goes, and the lead is cut to just one.

Leinster have really grown into the contest since Josh McKay's try, and they win another penalty, this time at the breakdown.

Harry Byrne calls for his kicking tee again.

Leinster's first real spell of possession in Glasgow's half sees them win a penalty, which fly-half Harry Byrne slots through the posts to get the visitors on the board.

Brilliant work from John McKee on the floor wins Leinster a penalty, and another Glasgow visit to the Leinster 22 yields no points.

Glasgow's lineout doesn't quite go to plan again, but Ross Molony can't hang on, and the home side have a scrum in a hugely promising position.

Big chance this.

Leinster look a wee bit shaky here.

Tommy O'Brien isn't expecting the pass, knocks-on, and Glasgow win a penalty at the resulting scrum.

Once again, Tom Jordan kicks to the corner.

Glasgow's first mistake of the contest lets Leinster off the hook, as Scott Cummings is pinged for infringement at the lineout.

A penalty goes Glasgow's way, and Tom Jordan kicks to the corner.

It's been a slick, confident start to the new season.

A gorgeous offload from Huw Jones releases Sebastian Cancelliere down the left and Glasgow are on the front foot immediately.

Stafford McDowall smashes his way over the gain-line and takes the hosts into Leinster's 22.

It might be happening in a parallel universe compared to the World Cup, but for URC fans this is a big day.

Glasgow have plenty of big names back from Scotland but Leinster have a very callow look to them.

A front row aged 21, 23 and 23 and a back-up front-row aged 22, 20 and 21. Jack Boyle is their loosehead and a player that everyone in Leinster is very, very excited about. Not huge but very dynamic. His battle with Zander Fagerson will be fascinating.

You'd have to fancy Glasgow but don't let Leinster's unfamiliarity fool you.

Leinster's last campaign promised so much, but ultimately ended in heartbreak.

Having topped the regular URC table, the Irish province then lost to Munster in the league semi-finals, before falling at the final hurdle in the Champions Cup for the second season running.

Silverware will be seen as an absolute must this season after such near-misses.
