Saints centre Dingwall: I don't actually think we were that great against Castres
Fraser Dingwall says he didn't actually think Saints were that great against Castres Olympique on Friday night.
But the England centre insists the belief continues to grow in the black, green and gold squad after the 49-41 Investec Champions Cup round-of-16 success at cinch Stadium at Franklin's Gardens.
Saints shipped six tries against Castres, but they were able to score seven of their own to secure a spot in the quarter-finals for a third successive season.
And Dingwall, who scored during the second half, said: "We're putting together some performances and this group grows together with each game.
"You see the more we connect, the more we get some good stuff on the pitch, it's constantly fuelling our belief.
"You see how the boys want to play and you see they're so invested in it. A lot of the time it's just how well we can do it.
"At times it was a little bit frustrating in this game because I don't actually think we were that great, but it's always nice if you're able to score a fair few tries."
Saints are now preparing for a quarter-final against the winners of the clash between Bath and Saracens.
And Dingwall said: "It will be an exciting game and it's kind of cool it's an all-English affair."
