In all there are 15 Ireland internationals in the province's squad, while Jonathan Sexton, who has accumulated 35 points in three games so far in this season's Heineken Cup, and South African prop CJ van der Linde both made their comebacks from injury in the victory over the French side.
Skipper Leo Cullen's next appearance in the Heineken Cup will be his 62nd in total and his 50th for his native province. The team is expected to be announced on Friday afternoon.
Meanwhile, in excess of 7,000 Leinster supporters are set to descend on London this weekend.
