Sunday 18 January, Kingsholm, 3.00pm kick off
The Blues currently sit top of their group, after picking up a maximum four wins out of four so far, but they face a tough trip to Guinness Premiership high-flyers Gloucester this weekend, where a win would guarantee their progression into the knock out stages.
Indeed a Cardiff Blues victory would all but confirm home advantage for the quarter-final draw. Director of Rugby, David Young is under no pretences about the importance of the Heineken Cup 'home factor' after narrowly missing out last season in their final pool match away to Bristol. One more try would have earned an Arms Park showdown for the Blues, instead of the daunting trip to three time champions Toulouse.
"It's huge, you've only got to look at the competition season on season," said Young.
"Although it has been done, very few teams actually get through to the semis via an away tie."
"While we probably saved up our worst Heineken Cup performance for the quarter-final last season, it was always going to be a big mountain for us to climb to go to Toulouse and win out there."
"After four games we are in a very good position, but we've still got work to do and our focus is to win our last two games. That's not going to be easy, but if we can do it we are more or less guaranteed a home quarter-final."
"It would be a big step for us to get that home tie which would give us a better and more realistic chance of progressing to the semis."
The Blues defeated Gloucester 37-24 in front of a record crowd of over 27,000 supporters back in October. However, the Cherry and Whites have lost only once at Kingsholm all season.
"We are going to Kingsholm to win," added Young. "If we do that, then we've got to feel that we've probably done enough. The pressure is certainly on them because they've got to win to have any chance of going though. People have talked about us going there and trying to get a bonus point, but you can't play for a bonus point."
"We've got to go and try and win this game and that's our mindset. It would just be a case of getting the result against Calvisano then."
"If we can't beat Calvisano at home we shouldn't be in the quarter-finals of the Heineken Cup anyway. That's not being disrespectful to them, that's just being truthful."
Sunday could see the continued recovery of Xavier Rush and Jamie Roberts, who both returned from injury against Leinster. It is also hoped that Martyn Williams and Ben Blair will be back earlier than expected for the crunch game at Gloucester.
