Leinster opened their European Champions Cup account with a win yesterday evening.
The Blues had to battle, though.
They came from 9 points down at half-time to beat Wasps 25-20 at the RDS.
The London side scored two tries in the first half, through Alapati Leiua and Christian Wade.
European debutante Darragh Fanning also touched down in the first half, as the Blues trailed 20-11 after the opening 40 minutes.
But Leinster fought back in the second half, as Fanning touched down again, while Dominic Ryan also went over.
Ian Madigan also kicked ten points as an injury-hit Leinster won by 25 points to 20.
The win puts Leinster joint-top of their group alongside Harlequins, who beat Castres 25-9 on Friday.
