22-6 down at half-time in the 2011 Heineken Cup final, Johnny Sexton stepped up to give his Leinster teamates a rousing speech which has since gone down in rugby lore.
Leinster won that game 33-22 with the Irish out-half's speech cited as a major factor in the turnaround.
Post-match, Sexton referenced Liverpool's comeback against AC Milan in the 2005 Champions League final, leading many to believe that he had mentioned it in his half-time speech and also that he was a Liverpool fan.
In an interview with Matt Cooper on Today FM, Sexton explained that he is actually a Man Utd and that his mention of Liverpool four years ago led to plenty of slagging from friends.
He also disclosed that John O'Shea believed him to be a Liverpool fan and that this 'killed him'.
I made the mistake after the game of mentioning it in the post-match press conference or on the pitch as I was getting interviewed because that was what was on my mind at the time. But I actually didn't say that in the dressing room.
I just said that in European finals or in big finals in sport, you see it all the time, that teams come back. I can't remember what exactly I said, it was so long ago now.
I have a lot of Man Utd supporting friends who texted me abusing me for mentioning Liverpool.
I did a thing with John O'Shea last week and he thought that I was a Liverpool fan. I obviously watched him growing up playing for Man Utd. I'm a massive fan of him and for him to think that I'm a Liverpool supporter killed me.
