England prop Alex Corbisiero says he came away with an "amazing experience" after being thrown in at the deep end against Italy.
The 22-year-old was handed his debut as a late replacement for Andrew Sheridan, who was ruled out with a back injury on Friday.
It meant that Corbisiero had just one day to prepare for his first start - a comfortable 59-13 win - which saw him pack down opposite experienced Italy front row Martin Castrogiovanni.
But the London Irish player believes that the nerves may have been worse if he had been given time to dwell on his selection.
"It was an amazing experience. It means a lot playing for your country. It was a great feeling - a real dream to be out there," Corbisiero said.
"They didn't make the decision I was playing until Friday morning.
"It was probably easier just getting chucked in than having a long build-up and having it dwell on your mind a bit.
"There weren't many scrums but I thought the set-piece was really good for us. We contested really well in the lineout well and I just got on with what I needed to do around the park.
"There is a lot of trust in the team. The boys trust each other to do their own role and that leaves you with a clear head to do your job. We were on the front foot and playing great rugby."
Sheridan is expected to return to the starting XV for the clash against France in two weeks' time but Corbisiero is still eager to resume his Test career.
He added: "You want to play for your country every time.
"Guys like Andrew Sheridan will probably be back. I stepped in and feel like I had a good performance. I have been lucky enough to get the opportunity to play this week."
