Leinster captain Johnny Sexton feels they still have plenty to work on after booking their place in a third successive Guinness PRO14 final.
The former world player of the year scored eight-points as Leo Cullen's side overcame their rivals Munster 13-3 behind closed doors at the Aviva Stadium.
It's a 24th win in-a-row for Leinster but Sexton believes they'll need to improve ahead of facing Ulster or Edinburgh in the decider and Saracens in the quarter-finals of the Heineken Champions Cup.
"We need to be better in areas but we showed some good stuff and some good courage," the Ireland captain told Eir Sport after the game.
"It was obviously a very difficult game in terms of conditions, the way that Munster play made it very difficult for us.
"Ultimately it's great to get a win, that's what you come into semi-finals for and thankfully we picked it up.
"We gave away some cheap penalties, so we need to work on discipline and the breakdown...there's also some areas we need to improve on in our attack.
"They made it very tough for us at the breakdown, it was very greasy, there were a few showers before the game which made the ball difficult to handle.
"It's a risk when when you play rugby in your own half, we did a few times in the second-half stupidly and nearly paid the price for it."
