Brian O'Driscoll may have won everything on the European stage, but he is determined to set the record straight in the one tournament where he believes he and Ireland have yet to make their mark - the World Cup.
The 33-year-old talismanic captain and centre has won two European Cups with Leinster, captained Ireland to only their second Five/Six Nations Grand Slam in 2009 and three other Triple Crowns, won a record 113 caps and last March broke the 78-year-old Five/Six Nations try record with his 25th.
Enough for most professional sportsmen to retire contented but not for BOD, as he is affectionately and irreverently known in his homeland and whose biography was titled 'In BoD we trust', as he is desperate to leave his imprint on the World Cup after three largely disappointing campaigns.
In 1999 he was just emerging as a star of the future - which he confirmed a year later with a hat-trick of tries for Ireland ending years of failure against the French in Paris - and in 2003 they were swept away by a Frederic Michalak-inspired France team in the quarterfinals.
However, it is the bitter memories of the 2007 edition when a over-confident and under-prepared squad bowed out humiliatingly in the first round, costing Eddie O'Sullivan his job and leaving O'Driscoll seething and vowing there will be no repeat this time round.
"It will be good to look back on the World Cup and be very proud of it," said O'Driscoll on IRFU TV.
"That we put our best foot forward and hopefully got good results. I'm not saying semis or final."
However, O'Driscoll - Ireland captain since the retirement of Keith Wood in 2003 - almost in the same breath then suggested that was exactly what he was aiming for.
"Our goal is to achieve what no other Irish team has done in a World Cup before.
"I will have been involved in four World Cups and realistically with this being my last I don't want to have been disappointing in all.
"It would leave a bit of a sour taste in my mouth. I want to look back and have no regrets in not achieving my ambitions in the World Cup."
O'Driscoll, who is willing to make sacrifices like when he declined the invitation to the Royal Wedding earlier this year sending actress wife Amy Huberman instead as he prepared for a European Cup semi-final, believes this squad is capable of delivering on it.
"With no disrespect to previous squads especially the 1999 one there wouldn't have been the calibre of players certainly not the numbers at the highest level to choose from," said O'Driscoll.
"We have moved on in the last 12 years."
O'Driscoll, who made a remarkable recovery from the serious shoulder injury he suffered after the infamous spear tackle on him in the opening minute of the first Lions test with the All Blacks in 2005, is also not unduly alarmed that the Irish have lost all three of their warm-up matches.
"We're not in the World Cup now," said O'Driscoll, who was speaking ahead of the fourth and final warm-up match against England.
"There would be pressure on us if we had lost our first three pool matches.
"I don't think any alarm bells will be pressed if we go into the World Cup with four defeats."
While it may be the final World Cup for O'Driscoll, the son of two doctors and who has two sisters, he says he will know when it is finally time to call it a day in a sport he has brought so much to.
"Once the tingle leaves you, it is time to hang up your boots."
