And having made an impressive start to his France career, Buttin admits it has been a whirlwind rise for him this season.

“I’m surprised that I wasn’t nervous. During the warm-up I felt good, and being a replacement took some of the pressure off,” said Buttin who was a member of the France Under-20’s squad in last year’s RBS 6 Nations.

“But when I came on I was amazed by the atmosphere.

“As soon as there was an attack you couldn’t hear anything. I had about ten matches with the age grade teams, and about 15 in the Top 14, so it’s gone quickly.

“This game, in a packed stadium will stay with me. I’m proud to have worn the shirt and I’ll keep that one to give to my parents.

“As soon as Clément [Poitrenaud] was hurt, Yannick [Bru] told me to warm up. Two minutes later I was on, I just had time to do a couple of sprints. It didn’t give me any time to think. I had the chance to get a fair amount of game time, that’s what I will remember.

“I didn’t start questioning myself at all.”
