Leinster head coach Leo Cullen is calling on his players to use tomorrow's meeting with Glasgow Warriors (live on RTÉ1 and RTÉ Player) to drive their own "internal competition", ahead of a busy block of games.

Tomorrow's visit of the Warriors is the first of 10 games in consecutive weeks for the province, with Champions Cup pool games dominating the next two-and-a-half months until the Six Nations.

Cullen is without his frontline internationals this week, those players given a week off after Ireland's Autumn Nations campaign.

However, they have been able to call on a number of first team regulars, with Rónan Kelleher back from injury at hooker, Ross Molony and Joe McCarthy in the second row, and Ross Byrne steering the ship at out-half.

And with a top of the table clash against Ulster to come next week, before Champions Cup meetings with Racing 92 and Gloucester, Cullen wants his players to take advantage of their chance to impress.

"We have a group playing against Glasgow that want to play in the biggest games coming up, they want to be in the European games, they want to be there for the Six Nations," the Leinster coach said.

"Everybody needs to be ready to take the opportunity. Joe McCarthy is back in with us this week, and we have a good competitive group, so it's about them making their time, to make memories individually and collectively.

"Glasgow are a very, very tough opponent that we've struggled with in the past. People will talk about the last time Glasgow came here, but it's a totally different time now. Conditions this time of year are tricky so we need to manage them well on the day, and it'll be a tough battle for us."

Kelleher returns at hooker having been out since September due to a hamstring injury, during which time Dan Sheehan has been in excellent form for both province and country.

Likewise, Harry Byrne is fit again after injury, and is in line for his first appearance of the season off the bench.

"Rónan has obviously been very unlucky with his injury but he's coming back now and he’ll be fresh coming into this big block of games coming up," the head coach added.

"It’s good to have those guys back in. Rónan played an early round and picked up what seemed like something innocuous at the time but he did a bit more damage. The other guys have been careful in managing him back in.

"Harry was due to play a club match before November and then he had a set-back. But he is back now and it is huge for the two lads who can hopefully play a part in the next 10 weeks."

After seven wins from seven in the opening block of games, Leinster have opened up an eight-point cushion over Ulster, who are in action tonight in Belfast against Zebre Parma.

And while Ulster could temporarily cut that deficit down to eight points tonight, Cullen says his side's main motivation is internal.

"We can't control what happens with other teams in the league, it's controlling our own part.

"There are lots of moving parts at the start of the season, we have a number of guys that will get a bit of time to freshen up this week, other teams will do it slightly differently. We'll come to what we're doing ourselves, so it's now about going out to deliver.

"We have the internal competition, and we want to be our own standards, we aren't too worried about what everyone else is doing.

"We just get to the standard we want to achieve, but Glasgow won't make it easier for us, Franco Smith is a very shrewd operator. He's a very experienced coach, and that's our focus.

"Where everyone sits in the league isn't relevant to us, we just want to focus on ourselves and accumulate as many points as we possibly can, and move onto the next week and do the same."

Leinster were 40-3 winners in a friendly v Chile last week

While it's four weeks since Leinster's last URC game, they did have a run-out versus World Cup-bound Chile in Donnybrook last Friday.

Six of tomorrow's starting team featured against the South Americans, while they also used the game to give an opportunity to some players from outside the provincial system who have excelled in the Energia All-Ireland League, with Clontarf's Cormac Daly, Terenure's Conall Boomer and Dublin University pair Thomas Connolly and Colm Hogan involved on the day.

And Cullen says the AIL is something they're keen to tap further into in the future.

"We’re watching a lot of our young guys in the AIL and then we’re also seeing other guys in the AIL who might be sparking our attention. So it’s a good opportunity to reward some of those players.

"Plus, some of them had already been in with us pre-season when we had the "A" campaign with all the Interpros, a mix of very young players and guys from the AIL because our internationals were away in New Zealand.

"Our numbers don’t change so if we have players picked for the national team, it leaves space in the building so it’s all about utilising that space.

"And to be fair I thought the club guys were outstanding, how they applied themselves, the eagerness they have to play, diligent with their off-field work.

"I have to say it was a really enjoyable week, a really, really enjoyable week, and I thought there was a lot of good stuff in the game as well. So it was, really, really pleasing and something that we'll definitely look at in the future," he added.
