Former Ireland captain Paul O'Connell was back in familiar surroundings this week as he joined the current senior team ahead of Sunday's Six Nations match against England at Twickenham.
Some of the Irish younger brigade had also previously worked with the ex-Munster second-row with hooker Ronan Kelleher among those to have been coached by him at Under-20 level when O'Connell had served as an assistant coach.
Kelleher had the chance to catch up with O'Connell during his week with the Irish squad.
"We were reminiscing about the '20s when he was my coach as well," said the Leinster front row.
"I picked up a good bit with him then. I remember his big thing back then was about visualisation.
"That was something that we brought through just as a squad back then as well and I still do it to this day really."
It has been a meteoric rise for Kelleher this season, having starred for Leinster, earning himself a call to the Ireland squad.
The 22-year-old will start from the bench at Twickenham and he has made sure to soak in the early experiences of Irish senior action over the past month.
"I've been taking it all in, all the experiences, over the last couple of weeks," he said.
"Just looking forward to getting over [to Twickenham]. A big stadium and one of the main away grounds in the world really.
"So I'm just looking forward to it really."
