Ireland coach Joe Schmidt has hailed his side's Six Nations triumph.
The Irish defeated France 22-20 at the Stade de France in Paris on Saturday, as Brian O'Driscoll ended his international career on a winning note.
"The fairytale continued right to the end for the magic man [O'Driscoll] and I'm just delighted for him," BBC Sport quotes Schmidt as saying.
"It's unbearable, I'm not sure I can last too long doing this job. The heart just about gave up.
"We've shown incredible discipline right through the tournament and I think it was a credit to the players today that they maintained their discipline right to the finish."
This was Ireland's first Six Nations success since the 2009 Grand Slam.
