The Heineken Cup may be the ultimate prize in the minds of this season's semi-finalists, but all four teams have a 'double' in mind as they reach the business end of their 2008/09 campaigns.
Just in case you needed any convincing that the Heineken Cup is about the best playing the best, the four teams that are left in the hunt for the 14th title are right at the top of their games.
Defending champions Munster, who inflicted that record 43-9 defeat on the Ospreys at Thomond Park on Sunday, are currently seven points clear of semi-final rivals Leinster at the top of the Magners League.
Reigning champions Leinster haven't given up hope of holding on to their crown in that competition, with four matches still to play and a possible 20 points up for grabs. But they also know that their Croke Park showdown with their biggest domestic rivals on 2 May will give them the chance to take a step nearer to winning the biggest prize in European rugby.
Leinster are the only one of the three Irish province who have played in the Heineken Cup not to have reached the final and they will be hoping it will be fourth time lucky in the last four next month.
While Munster and Lienster are chasing a Heineken Cup and Magners League double, Cardiff Blues are into new territory as they try to capture two trophies.
The Blues, who face a third Heineken Cup tie at the Millennium Stadium this season when they meet Leicester Tigers in the second semi-final, will get a taste of cup final action when they travel to Twickenham Stadium this weekend to meet Gloucester in the EDF Energy Cup final.
It is the first time as a region that the Blues have made it to a final and their quest is to go one better than Cardiff did in 1996 and win the Heineken Cup. The Blues have already trumped the Class of '96 by beating Toulouse - it was the French side that beat Jonathan Humphreys' team in that inaugural Heineken Cup final at the old Cardiff Arms Park - and they are going to have to win the European title the hard way.
Having beaten three times winners Toulouse in the quarter-finals they now face two times champions the Tigers in the semi-finals. Then they could meet the reigning champions, Munster, in the final at Murrayfield Stadium.
No team has ever won all nine games en route to lifting the Heineken Cup since the tournament went to home and away matches in the Pool stages. The Blues have now won seven in a row.
As for the Tigers, their double quest includes hoping to scoop a third Heineken Cup title and claiming the Guinness Premiership crown. They currently top the Guinness Premiership with 62 points and, with two games left to play, look set for a home semi-final.
The Heineken Cup - where the best plays the best to find out who is the greatest.
