Speaking ahead of the trip north to Belfast, Leinster consultant coach Alan Gaffney said that the squad are determined to maintain top spot in the Magners League against an improved Ulster side.
"There will be some tough selections in both the backs and forwards this week, which is good because it breeds competition in training and it keeps all the players on their toes," said Gaffney.
" It was encouraging for someone like Kev (McLaughlin) to come in against Brive and perform as he did coming off the bench, while it was also good for CJ (van der Linde) to get some game time because he's a world class player who can make a big impact for us this season.
"We face an exciting test against an Ulster side who have been in impressive form recently. Though Leinster have a good record up in Ravenhill of late, it is a difficult place to play and it is an even tougher place to win.
"They performed strongly against Bath the week before last and were unlucky by all accounts not to get a win against Edinburgh on Saturday.
"They probably feel as though they should have walked away with the spoils, which is no mean feat because Murrayfield is a tough place to get a win.
"Guys like Tom Court, BJ Botha and Andy Kyriacou are supplemented by the likes of Isaac Boss, Andrew Trimble and Paddy Wallace who have been around for a long time.
"Ulster are going to be tough opponents because they are a side on the up. We will need to be accurate and physical in our approach this weekend and the players are aware of the need to improve."
The Leinster team is expected to be named on Friday afternoon.
