Ireland will prepare for another World Cup meeting with Six Nations rivals Scotland after wins over Gregor Townsend’s side in 2019 and 2023.
The Irish have never faced Uruguay at Test level, while they thrashed Portugal 106-7 when the sides met in Lisbon in July.
“Scotland have performed well in the last couple of tournaments, so that’s a great fixture,” added Farrell.
“We know each other well and will continue to do so in the coming years. But Uruguay and Portugal are a little different. We’ve played Portugal once and I’ve actually tried to play against them a few times, so we’ve followed their journey.
“Uruguay is a little different. All in all, I was super excited. I got goosebumps standing up, as in it’s exciting, you know. So that’s the way it should be.”
Expanding on the rivalry with Scotland, who Ireland have beaten 11 times in a row, Farrell added: “The easy thing for us to say every time we play Scotland is that we have always had a lot of respect for them as an unbelievably dangerous, world-class side.
“Having worked with many of their players in the summer [with the British and Irish Lions], you get to see why you [Scotland] feel like that.
“Obviously, knowing a few more guys, there’s insight there both ways, but I suppose over the course of two years those things change massively as well.”
