After surviving a bit of a scare against Lyon, Jordan Larmour is expecting another tough encounter when Leinster travel to face Northampton Saints in Round 3 of the European Champions Cup on Saturday.

Franklin's Gardens will stage a contest between the two unbeaten sides in Pool 1, with Northampton also pushed all the way when seeing off a spirited Treviso side the last day.

Assessing the Saints ahead of the weekend, Larmour said: "They're a very good attacking side with a good kicking game and good defence. We're going to have to be switched on and to come up with a good game plan. 

"This will probably be our toughest challenge yet.

"We always put pressure on ourselves to perform. We've got a bit of momentum now but it's just important that we forget about that... put it behind us and focus all our attention on two big weeks.

"We have high standards, and we need to live up to them. 

"It's hugely exciting. Both teams have been going well. Every point counts. It's important we're switched on and we bring it.

"We're just focusing on how to beat Northampton. We'll do our homework, see where we can exploit our game plan. Come Saturday, the better team will win."

Larmour also highlighted the good spirit within the camp, with Leinster also going well in the Pro14.

"We're building nicely and everyone's looking forward to getting back on the pitch this week," he added.

"There's always different things you can work on. It's important we fix them on the training pitch. Last week we had about 44 people in training so there's massive competition and standards are high.

"I'm enjoying my rugby at the moment. As long as I'm getting game time, I don't really mind where I'm playing. 

"You need games to be getting better. It's in the games where you really show yourself."
