Leinster made it four from four in the Investec Champions Cup and guaranteed a home tie in round of 16 with a 27-10 win at Leicester.
They finish top of Pool 4 with 19 points out of a possible 20.
Leo Cullen's side now wait to find out their opponents as the group stages come to an end tomorrow evening.
The visitors fought back from an early 10-0 deficit to take the lead, scoring two tries in either half.
Joe McCarthy and Jordan Larmour bagged first-half tries and Harry Byrne kicked a penalty and a conversion to give them a 15-10 lead at the break.
Tries at the start and end of the second half, from Dan Sheehan and Caelan Doris, meant Leinster left with all five points, which could be crucial in securing home ties should they advance beyond the next round.
There was little in the way of adventure in the opening exchanges as the sides felt each other out.
However, that all changed in the blink of an eye when Leicester spotted a numbers advantage off a ruck just inside the Leinster half.
Centre Dan Kelly picked from the base and had plenty of support with Larmour desperately calling for help. But it was too late and Hanro Liebenberg [below] had a simple run-in; Handre Pollard converted.
That was the spark the game needed and Leinster almost responded immediately but Andrew Porter got held up over the line.
Pollard pushed the Tigers lead out to 10 in the 21st minute, punishing Sheehan’s illegal play on the scrum-half with a long-range penalty.
But Leinster soon found their footing and Byrne got the four-time champions on the board with a penalty.
Byrne was growing into the game and good play by Larmour and player of the match James Lowe forced Leicester to concede a couple of penalties.
From a clean lineout, McCarthy [above] powered over with referee Andre Piardi brushing off complaints that the lock had not released after an initial tackle.
Another powerful Lowe run freed Garry Ringrose and Jamison Gibson-Park before Tadhg Furlong made more hard yards.
The ball came to Larmour [below] on the far wing and the Ireland call-up sidestepped his way over and Leinster held a deserved 15-10 lead at the break.
Dan McKellar’s side got off to a faster start but a basic error paved the way for the visitors to put some distance between the sides.
Pollard missed a penalty kick to touch and in a matter of moments, Leinster were on the attack.
Scrum-half Tom Whiteley went to the bin after slapping the ball away as Leinster threatened on the short side.
From a lineout maul, Sheehan peeled off and crashed over for their third try, this time converted by Byrne.
It became scrappy for the next 20 minutes with replacements and errors not allowing the Tigers to find any rhythm.
Sam Prendergast replaced Byrne [above] with 16 minutes to play, the starting out-half limping off and perhaps causing some concern for Ireland head coach Andy Farrell. Byrne had just recovered from a foot injury.
Replacement Jack Conan went in the bin soon after as Tigers piled the pressure on close to the line but Doris came up with a huge turnover to ease the pressure.
The hosts tried hard to get to within bonus territory but a poor lineout and good Leinster defence held them out.
Leinster won a penalty with the clock in the red but lost possession from the lineout, however, neither side could hold onto it and Cullen’s side showed their class by keeping the ball alive long enough to stretch the Tigers defence and Doris crashed over in the last action of the game.
