Scarlets number eight John Barclay agreed with head coach Wayne Pivac's view that their performance against Leinster was one of their best to date.
Their 23-13 victory over the Irish province at Parc y Scarlets saw Barclay and openside flanker James Davies stand out, the former scoring on Saturday.
And Barclay, who was left out of Scotland's squad for the Six Nations, believes the team can build on this impressive effort in the PRO12 campaign run-in.
"We didn't hide away from the fact that it was a huge game. We've got to get into the top six. A club like this needs to be playing in the top flight," he said.
"We talked it up and the pleasing thing was we really delivered. Points wise we've had 12 from the last four games so effectively we're three from four. It's really pleasing."
Reigning PRO12 champions Leinster travelled to Parc y Scarlets with strength in depth right across the park. Scarlets' victory over such a strong Irish side was all the more pleasing according to Barclay due to that fact.
"They weren't far from full strength – that makes the performance even better, even more special," he added.
"I think it was one of our best performances of the year. I thought we played really well to a man. We kept playing and playing. We could have got the bonus point but we were happy to get the win.
"Our defence was great, a few guys have come through like Cubby (James Davies) and Lewis (Rawlins) – these guys are really stepping up.
"It's great for this year and next year with these guys coming through. I play the way I play; Cubby is playing well so we feed off each other. We've also got Shings (Aaron Shingler) and Rob (McCusker) – we've got quite a bit of depth here."
On his own form and being snubbed by Barclay, he added: "I definitely want to play for Scotland. I think I'm playing pretty well but obviously not good enough at the moment.
"I'm happy down here, really happy at the club. I'll just keep my head down; if I get called up I'd love it. I think I've got a lot to offer still. I enjoy playing here, if I was at a club I wasn't happy at that may be playing on my mind more."
