Cardiff head coach Matt Sherratt: “This is an opportunity for us to sign off the season in style with back-to-back wins.
“We’ve played some good rugby this year, but it hasn’t always translated to wins despite some very near losses.
“Judgement Day is always a special occasion in the Welsh rugby calendar and if we can secure a victory against a strong Ospreys side in front of a big crowd, it will be a nice way to round off the season and give us some momentum into next year.”
Ospreys head coach Toby Booth: “There is nothing we can do about results elsewhere.
“We can only control what we do. If we end up falling short, that will just give us the motivation to keep going.
“We are trying to become a top-eight team and that’s the next line in the sand for progress.
“We have improved this season. We have won more games and everyone in the group should take a lot of credit for that.”
