Speaking ahead of the match Cardiff Blues Director of Rugby David Young said, "It is testament to all the hard work put in by the players and the coaching team and the off field staff how much the team and region has grown over recent seasons."
"We are thrilled to be in the semi-finals and enjoyed our day last Saturday but our feet are firmly on the ground. We haven't won anything yet and we are fully focused on the match against Gloucester."
"Although we have beaten them twice this season, we would be foolish to underestimate them. We have huge respect for them and know they are a better team than when we played them in the Heineken Cup."
