Cardiff head coach Matt Sherratt: “I think being back in the Principality is massive.

“It’s the home of rugby in Wales, right in the middle of the city, and you’re getting the four regional teams with the best Welsh players under one roof on one day.

“There’s three teams vying for the top eight, that’s something I haven’t experienced before.

“To have ourselves, Ospreys and Scarlets all in the middle of the table with something to play for adds that extra bit of spice.”

Cardiff captain Liam Belcher: “There’s always a bit of an edge in any derby, whether there’s something on it or not, we’re all around about the same points tally. With four games left every point matters. If we come out with a win it puts us in great stead going forward.

“The best Judgement Day I had was two years ago. A lot of the boys were leaving, and to send them off with a win was unbelievable. To end that season on that high was amazing.

“The way the Ospreys play at the moment is quite expansive, it’s great to watch. We like to think we play a nice exciting fast game, so for the neutral fans it’ll be a very good exciting opening game.”
