Leinster captain Isa Nacewa says he was heartened by the sight of his teammates celebrating an historic cup double with their families in what was his final appearance for the club.

Leo Cullen's side put five tries past Scarlets to claim the Guinness Pro14 title just one two weeks after their Champions Cup triumph against Racing 92 to send Nacewa off in style.

They are the first team to achieve this feat, and the Kiwi was able to savour the success on the pitch with his children, a moment which he say's he'll 'never forget.'

"[I feel] joy for everyone involved in helping today come about - 55 players used this season, " he told RTÉ Sport. 

"Seeing guys celebrate with their families in what was a slog of a season is pretty special so it's a massive day for the club, backroom staff.

"Everyone that's connected to this, it's a special day. For guys to spend it with their families is awesome.

"For my wife Simone to bring the girls down to pitch-side was a day I'll never forget. They've never been on the pitch, I've never brought them on the pitch and to do it here in Dublin in front of everyone, it's going to be a great photo for the photo album."

The Leinster stalwart says he has no immediate holiday plans to help him unwind from what has been an intense end to the season, and will instead be returning to 'normal routine and Dad routine.'

Nacewa was withdrawn after just 20 minutes in the final at the Aviva Stadium after picking up an injury, and was treated to a standing ovation as he made his way off the pitch.

His departure was similar to that of former Leinster captain Brian O'Driscoll, who lasted just eight minutes in his final game in a blue jersey back in 2014.

Incidentally, Nacewa said he joked about that when he he spoke to O'Driscoll earlier this week.

"The body completely let me down," he laughs, "and I saw Drico during the week and we did have a little laugh about that so I'm sure the next time we catch up I'll try and top him and say that I got to 20."

Nacewa says that Leinster has been evolving as a club since he arrived a decade ago and admits that winning the Champions Cup and Pro14 was a goal they targeted at the outset of the season.

He expects to see Leinster regroup and chase more success in 2019 after what they achieved this year, and confesses that he never envisaged his time at the Irish club to turn out like this.

"I didn't know it was going to be this way but when you join such a great club with such a proud history, you just join the culture and get on board with the way things are done. It's special for me and my family so it's definitely days to remember."
