Leinster head coach Matt O'Connor pinpointed Bryan Habana's intercept try as the moment the tide turned in Toulon's favour in their Champions Cup semi-final clash in Marseille.
That try, allied to a conversion from Leigh Halfpenny, left Leinster trailing Toulon 25-15 with ten minutes of extra-time remaining. And although the Irish side pulled back a try through blindside flanker Sean O'Brien, ultimately the gap proved too big to close.
O'Connor said. "The effort the lads put in was fantastic and we are obviously incredibly disappointed to come second.
"Habana's intercept was the turning point - he is world-class - but the positive for us was the effort. It was second to none.
"A lot of people had written us off coming into this game but we will back ourselves to go anywhere and beat anybody."
Leinster skipper Jamie Heaslip added: "It felt like a boxing match out there. There was nothing between the sides.
"We probably left opportunities out there in the first 40 minutes and they had a purple patch in the first 20 minutes of the second half, but we stood our ground.
"We always have an inner belief that if each player does their job, we are a good team and we can create situations to get some points."
"The intensity and physicality today was right up there with an international match. It was touch and go throughout and games sometimes are decided by very small margins" - Leigh Halfpenny
Halfpenny, who slotted six penalties and a conversion for the French team, revealed post-match that it was for this kind of occasion that he signed for the double European champions.
"As a professional rugby player, something like this is what you grow up dreaming of," said Halfpenny, who joined Toulon from Cardiff Blues last summer.
"You work hard day in, day out to be involved in the big matches, and the success and ambition of Toulon, I felt that I wanted to be a part of that.
"I was fortunate to be given the opportunity and it was a challenge I felt that I needed. To be rubbing shoulders with these guys, I can only feel it is helping my game.
"The intensity and physicality today was right up there with an international match. It was touch and go throughout and games sometimes are decided by very small margins.
"You could not switch off for one second and credit to the boys. The character they showed was immense."
Halfpenny was part of the Blues team that lost a 2009 semi-final penalty shoot-out against Leicester in Cardiff, and he added: "I did think of that and I thought 'here we go again'.
"But Bryan read that pass superbly and luckily we didn't have to go to a penalty shoot-out this time."
Not our most clinical performance eva but proud of the effort none the less. Hats off to @jamieheaslip and his boys for their effort as well— Bryan Habana (@BryanHabana) April 19, 2015
Toulon boss Bernard Laporte said: "I feel very relieved indeed. It was not easy, and we were a bit vulnerable.
"We made a lot of mistakes - on a better day we might have won the game by a bigger score - but we showed tremendous spirit.
"There are not many games at this level that you play during a season and it is the team that makes fewest mistakes that mostly comes out on top."
