He may have nearly half a century of international caps and a Lions tour under his belt, but, Wales' Liam Williams still defers to the great knowledge of Ireland's Johnny Sexton.
Known affectionately as 'coach' by Williams, the Saracens man revealed to Wales Online that he is still hoping to share "a couple of pints" with Sexton after the "war in the afternoon."
Ahead of Wales trip to Dublin to face Ireland in the third round of this year's Six Nations, Williams spoke of the friendship he struck up with Sexton during last year's Lions tour of New Zealand:
Johnny would be the one I probably got closest to. Him and Owen Farrell led things and they're two world-class No,10s.
Johnny is a great bloke, I always call him 'my coach' and I'll do so again at the weekend!
On the comeback trail from a "frustrating" injury, today will be Williams' first appearance for Wales in this year's Six Nations.
By the sounds of it, the trip to Dublin is one that he is looking forward to; if not just a little tentatively:
The Aviva is up there are one of the best stadiums in the the world, it's always a great atmosphere. The Irish crowd can get on your back, but it's like that in every away game.
You go out there and you don't tend to think too much about the crowd, you just get on with your game.
Having also struck up a friendship with Ireland's Conor Murray during the drawn tour last summer, Williams is under no illusions that those relationships will be put firmly on hold for the duration of this afternoon's tie:
With Conor Murray at nine and Johnny Sexton at ten, they are two world-class players and I'm looking forward to the aerial battle against them.
Losing in unfortunate circumstances to England after hammering Scotland in the opening weekend, Wales come to Dublin knowing that a win is essential if they wish to propel their Championship push beyond week three.
