Cardiff Blues director of rugby Dai Young says their European two wins over Gloucester this season will count for nothing in the EDF Energy Cup final.
The Welsh region beat the Cherry and Whites home and away in the Heineken Cup pool stage.
"It's irrelevant in my preparation whether we're favourites or underdogs," said Young.
"One thing I'll be hammering home to the players is although we've beaten them [Gloucester] twice, by their own admission they didn't feel that they played well.
"They feel that they can probably bring a lot more to the table.
"I think we're going to play a lot better team come Saturday than we probably have previously, so I'm expecting a much tougher game and we're going to have to be better then the two previous meetings."
"The challenge is going to be us to sustain that level of performance, that level of commitment [they showed against Toulouse].
"It's a big ask for us but it's one we've got to live up to, to achieve something."
