Ireland and Leinster prop Jack McGrath has had a meteoric rise over the last 12 months.
The 25-year-old Dubliner has gone from being the deputy to Cian Healy to the man who is keeping Healy out of the Irish starting 15.
McGrath made 5 appearances off the bench on the way to winning the Six Nations in 2014 but this year as Ireland continue their quest for a Grand Slam, he is set to make his fourth start against Wales on Saturday.
Ahead of the trip to Cardiff McGrath spoke to 98FM Sport's Stephen Doyle about the Welsh scrum and the influence of Paul O'Connell ahead of his 100th international cap
