Felipe Contepomi had little difficulty in transferring his World Cup form to the European Cup as he inspired Leinster to an impressive 22-9 Pool Six win over former champions Leicester.
The Argentinian star landed six kicks out of eight and had a hand in the only try of this bruising encounter - winger Shane Horgan's 53rd-minute effort - as Leinster gained some revenge for their 2005 quarter-final exit at the hands of the English giants.
Hampered by a string of unforced errors, bad decision-making and some poor discipline, Leicester paid the price for a lacklustre second half performance as fly half Andy Goode kicked a single penalty to add to his first half haul of two.
Watched by new coach Marcelo Loffreda, Leicester were forced into a late change before kick-off. With Dan Hipkiss ruled out due to flu, Ireland 'A' winger Johne Murphy was promoted from the bench and Fijian star Seru Rabeni switched to his international position of centre.
Facing into a stiff wind, the hosts showed some good handling before Leicester prop Julian White was penalised for dropping a scrum and Contepomi kicked his side into the lead from 40 metres out.
Two big hits from Rabeni on Gordon D'Arcy and Contepomi set up a penalty chance for Goode, which he easily slotted, and Tigers went 6-3 in front in the 17th-minute with an excellent 45-metre penalty hit from their number 10.
Leicester were holding the edge up front but Leinster looked the more potent in open play with a Horgan break and a beautifully placed kick over the top from O'Driscoll forcing Goode into a rushed clearance behind his try line.
The attack ended with D'Arcy smashed by an Alesana Tuilagi tackle but Leinster gained a penalty award for an earlier ruck offence and Contepomi, from the central position, levelled as the first quarter ended.
Contepomi missed his third shot at the posts before the visitors gained a kickable penalty at the other end, which Goode slammed to touch. But Leinster won a relieving penalty with Frank Murphy delaying his put-in at a subsequent scrum and the hosts also kept Tuilagi and Ben Kay out in injury-time.
Leinster upped the tempo on the restart with Contepomi immediately converting his third penalty and, with Ollie Smith penalised for holding on at a ruck, the Argentinian soon made it 12-6.
With errors creeping into the visitors' game, Leinster took full advantage with O'Driscoll and Contepomi instigating the move that sent Horgan clear down the right touchline for his try.
Contepomi conjured up a fantastic conversion kick from the touchline for a 19-6 buffer and Tigers, who had won eight of their previous nine games in the competition, were in serious trouble.
Goode took the edge off Leinster's spell of pressure with a penalty, but that was only after last season's runners-up failed to capitalise when camped near the hosts' whitewash.
As Leinster worked their way back downfield, a ruck offence from Lewis Moody close to his posts saw Contepomi kick the Irish province further clear with a victory-clinching 69th-minute penalty.
