An injured Brian O'Driscoll missed Leinster's 2013 Amlin Challenge Cup final victory - the last European cup final the province contested.
Speaking on BT Sport's Rugby Tonight podcast along with Lawrence Dallaglio, O'Driscoll disclosed that he had briefly considered purchasing a Chelsea kit and having it under his seat for the game against Stade Francais.
A year earlier, a suspended John Terry had famously worn a full Chelsea kit for his side's Champions League final victory celebrations.
I'll tell you the one, the fourth one [European final] was a bit of a non-event. I didn't actually play in the final so on a technicality, it might just be three.
What I did think about doing on the fourth one was sitting on the couch that afternoon with my wife - and I genuinely did - I thought to her, 'Will I go down to Dundrum Shopping Centre and buy a Chelsea kit? Have it under my seat in the stand.'
It would be absolutely hilarious. We were wearing a similar colour blue. So I thought, 'Will I? Won't I?' It probably is being disrespectful to the tournament if you did that and as well, I'm 33 or 34-years-old. Maybe in your mid-20s you'd get away with it but I just thought, 'Maybe I'm a bit long in the tooth to be getting away with that sort of thing.'
It would have made something of that because it was a non-event. For any player that doesn't play in a final, it doesn't feel the same; it doesn't feel like you've properly won it.
The story popped up when Dallaglio asked O'Driscoll about his most humbling moment in European rugby. His most humbling moments included playing out-half for Leinster while taking a 50-point beating from Toulouse and also the 2006 semi-final defeat to Munster.
