"We are in a really tough Pool - and there is certainly no easy road to the knock-out stages - but it is a great challenge and we will just take each game as they come," he said
"The Scarlets are a team who really like to play attacking rugby and the form so many of their backs showed at the World Cup - players like George North, Jon Davies, Scott Williams and Rhys Priestland - shows they are sure to be really dangerous with the ball in hand.
"However, we have got a big, ball-winning pack so it will be down to us to try and deny them as much possession as possible."
Outside half Priestland is struggling with the shoulder damage that kept him out of Wales' final two matches in New Zealand, the semi-final and Bronze Medal matches, with Stephen Jones directing matters from No 10.
"The Heineken Cup is a tremendous tournament in which to be involved," said Masoe. "There are so many international players and quality teams that you really do find out just where you stand in European club rugby and not just in your own country.
"We have to start the tournament by targeting qualification for the quarter-finals but the Scarlets are going to be tough opposition - they really love their rugby and it should be an exciting occasion.
"We had a great start in the Top 14, winning seven of our first eight Top 14 matches, and, although we let ourselves down in a couple of recent games, I am confident we can bounce back on Saturday against the Scarlets."
