And this Saturday could see Davies return to the scene of that triumph as the Scarlets take on Newport Gwent Dragons at the Millennium Stadium, with Cardiff Blues and Ospreys battling it out straight after in a Welsh double header.
If he does feature it will be Davies' first taste of RaboDirect PRO12 action since playing the full 80 minutes against Ulster in January, while he will also be making his 100th appearance for Scarlets.
And as he returns to Wales' national stadium Davies' thoughts turn to finally winning silverware for the club he has spent his entire career at.
"I've grown up supporting the Scarlets and the players there are the ones you train with week in week out, so to get a taste of success with them would be particularly sweet," said Davies, whose Scarlets head into the weekend sitting fifth in the RaboDirect PRO12 table.
"I've spoken to the Ospreys players when we've been in camp with Wales, they've won this league more times than anyone and they say that winning silverware with your region is pretty special.
"Success with the Scarlets is definitely something that is important for me, we have a great squad and winning with Wales just makes you all the more determined to reproduce that with your region.
"We are all determined to put that right with a good run at the business end of the season to get us into the those play-offs and that means putting a performance together against the Dragons on Saturday.
"It will be strange to come back to the Millennium Stadium so soon after the incredible highs of winning the Championship here, but this is a special place.
"The atmosphere is always amazing and if the fans are anything like they were for the England game we should all be in for a real treat."
