Newport Gwent Dragons' recent record against Leinster actually makes for pretty reading after beating them twice last season.
And 29-year-old Landman admits the Dragons will need to replicate the performances against the Irish outfit in 2014-15 to get a result.
"I watched the Zebre game back and it wasn't like we weren't creating opportunities, it's just that we wasted them," Landman told the South Wales Argus.
"That makes you frustrated and then that was made worse by them slowing everything down. Against Leinster we need to make sure that when we get in the 22 we leave with points.
"Leinster won't underestimate us this time but I think that was the same when they came to Rodney Parade in April and we won.
"We know it will be a tough game and they will have a strong side even though they are affected by World Cup call-ups. They've got depth and a big budget but last season gives us confidence."
