Ahead of the huge fixture Farrell admits they will be taking the game to the English side as they look to progress to a first final since 2008.
“It’s our record 14th semi-final, but we can’t go into this one with the same mindset we previously have had,” the 26-year-old told EPC Rugby ahead of the weekend. “You can’t go out into these games and sit back and hope to win. We have got to enforce our game on them.
“The boys are extremely hungry, especially the ones that have been there, like Keith Earls. There’s an aura around weeks like this when Munster can progress in Europe.”
Munster come into this game on the back of a PRO14 win at Benetton while they beat Edinburgh in their European quarter-final to set up this date with Saracens, who Farrell knows will be a formidable opponent.
“They are consistently a really physical side, so that will be key for us is to stop their momentum,” he added. “They rely on set-piece and the contact area.
“They have been one of the biggest forces in Europe in the last few years and won every game in the pool stages, but we won’t be giving anything away.”
