The Tigers are coming to town but they face the toughest of tasks in the form of a Leinster side that are specialists in getting the job done at this stage of proceedings.
It's hard to look at the hosts' recent record against Leicester, and indeed the knockout stages of the Investec Champions Cup, and not conclude that taking care of business in this tie with the minimum of fuss is well within their repertoire.
This is the stage where Leinster purr.
They have played 14 play-off games in Europe since their last Champions Cup success in 2018, the victory over Racing 92 in a rainy Bilbao that seems a lifetime ago now.
They've reached the final three times, playing 14 games in total, winning nine and losing five; those painful defeats coming against just two sides: Saracens in 2019 and 2020, and La Rochelle in each of the last three seasons.
Each year, it's supposed to be their year and it's taken the brute strength of Sarries and Stade Rochelais to deny them what they feel is their just desserts: a single European trophy in 12 seasons put them on par with Exeter in terms of silverware.
To get an idea of the expectation on Leicester to earn a first victory over Leinster in 16 years today, you could listen to the BBC and The Times rugby podcasts and it would take up 56 seconds of your day.
The various pundits are, however, gushing over Northampton, who host Munster on Sunday afternoon.
This evening's tie is the teams' second meeting in 12 weeks and their third in the last three years, each time Leo Cullen's side coming up trumps.
Leinster warmed up for the latest match-up by running up a pretty score against a strong Bulls outfit in the URC last weekend.
The four-time European champions ran in seven tries and alongside their 16-9 away win at La Rochelle in the pool stages it was their best showing of the season.
On the same Friday night, Dan McKellar's men went to Newcastle and came away with a hard-fought 19-13 win over the Falcons in a game that ran to almost 100 minutes and included a phenomenal defensive set by the Tigers at the death to claim the points.
Leinster issued a lengthy injury bulletin earlier in the week but have been able to call on fit-again Hugo Keenan, Andrew Porter and Ciarán Frawley, while Robbie Henshaw passed his return-to-play protocols.
Ross Byrne gets the nod at out-half ahead of brother Harry, above him in the Ireland pecking order.
McKellar, who began his coaching career with Wicklow RFC back in 2001, has been spending time this week criticising the competition's format, which sees five repeat fixtures from the group stages with more in the pipeline.
The Australian (above), in his first year in charge, has a fair point but this close to the game it may come across as getting an excuse in early.
Leinster beat Tigers 27-10 in January's meeting at Welford Road.
"Something is not right," he said.
"That is the whole reason why you have pools so you have a bit of variety. But it is what it is.
"We have got to play Leinster this week in Dublin. They have earned the right to host it at home and we will go over there with the intent to create an upset because I don't think a whole lot of people expect us to win."
Seventh in the Premiership and also this week fined for breaching salary cap regulations back in 2019, the 2001 and 2002 winners, will have to pull out something special to upset a 16-point underdog status.
They'll attempt to do so with just one of the three England forwards who started the win over Ireland last month with Dan Cole in but influential pair George Martin and Ollie Chessum are not in the squad.
They’ll also be without the same motivation to perform that Steve Borthwick's side had on that day, a major factor in that Twickenham shock.
"There is a target on our back no matter who we come up against," Leinster and Ireland wing James Lowe said.
"Leicester have a wealth of experience.
"They've got a World Cup winner [Handre Pollard] at 10; Freddie Steward at the back.
James Lowe responds to questions about Leinster players' tackle technique, following head injuries to Luke McGrath and Robbie Henshaw against the Bulls on Friday.

"We are under no illusion about the beast that is coming this week and we are going to prepare as if there's no tomorrow because if we don't perform there is no next week.
"Complacency is a killer. There is none of that in this camp.
"There is an expectation at this club to perform at the highest level. You get given everything to perform so there's no reason why you shouldn't. All the information is there, all the homework is done.
"It's about execution. It's Champions Cup football, something that we haven't won in many a year and we understand that we put ourselves in a position to play in front of our own fans and we're not here to disappoint."
The game kicks off at 8pm at the Aviva Stadium.
