Brian O'Driscoll believes his old Ireland colleague and Munster rival Ronan O'Gara will relish a crack at Leinster in the Heineken Champions Cup semi-final in three weeks' time.
O'Gara's La Rochelle will host the four-time champions in a mouth-watering last four tie, with Toulouse hosting Bordeaux-Begles in the other semi-final.
The French side are in the semi-final for the first time on the back of a sensational 45-21 win at home to Sale Sharks, but O'Driscoll believes they'll face a tougher opponent in his former province.
However, he says O'Gara will be licking his lips at the prospect.
"Straight away you think ROG v Leinster, we had so many tussles with his Munster side. They had the edge on us at the beginning, Leinster managed to turn it around," he said.
"Now, as a coach, I think he'll relish taking on a highly-fancied Leinster team over in La Rochelle. The brand he's got his team playing, Leinster don't come across that very often. It's all-encompassing, it's fast, it's frenetic.
"I do feel as though they'll look at the teams that beat La Rochelle - Exeter had a great victory there last season - and they'll try and understand what they managed to do to unlock them in their back yard."
Two tries in the opening 12 minutes of the second half from wing Raymond Rhule put paid to Sale's hopes on Saturday and ensured La Rochelle reached the last four of the competition for the first time.
