The former Buccaneers player is thrilled to have overcome the defending European champions.
Robbie Henshaw believes the "insane" atmosphere at the Aviva Stadium played a major role in Leinster's win against La Rochelle last weekend.
The Athlone man played a pivotal role in a defensive effort that saw his side keep the French club scoreless for the entirety of the second half.
Henshaw also produced a sumptuous cross-field kick for James Lowe's hat-trick try to seal a 40-13 victory.
He says it was a special day:
Leinster will return to Champions Cup action in the semi final at Croke Park against Northampton Saints on Saturday May 4th.
Robbie Henshaw was speaking at the Vision Ireland shop in Mullingar to promote their 'Skip the Skip' initiative which highlights the importance of donating pre-loved furniture and homewares to combat waste and support sustainable living.
