Jenkins remembers "crazy day"
It might have happened 10 years ago this month - but Wales prop Gethin Jenkins still remembers the occasion as "a crazy, crazy day."
The event in question was Wales' 2005 Six Nations title and Grand Slam-clinching victory over Millennium Stadium visitors Ireland.
Jenkins scored a try as Wales prevailed 32-20, securing a first championship clean sweep since the glory days of 1978 when players like Gareth Edwards, Phil Bennett. JPR Williams and Graham Price were in their pomp.
Fast forward to March 2015, Jenkins now has more than 100 caps to his name and Wales have won two further Grand Slams, while Ireland's Cardiff arrival this weekend once again sees the stakes raised.
This time, Wales must win to keep their Six Nations title hopes alive while Ireland need victory on Saturday and then against Scotland at Murrayfield next week to secure a first Grand Slam since 2009 - when they beat Wales in Cardiff.
"It was a long time ago, a crazy, crazy day," said Jenkins, who packs down in the Wales front-row this weekend alongside Scott Baldwin and Samson Lee.
"It was the first time (Grand Slam) for Wales in I don't know how many years. It was a magical atmosphere and a great occasion.
"Ten years on, there is a little bit of a different scenario. We, I suppose, are the underdogs here - Ireland have got it all to lose.
"We are obviously looking to win the championship, but we have to put a good performance in to beat them because they have been on top of us the last couple of years.
"They have been the most successful team over the last couple of years, and you know you are in for a tough game. When that is the case, games get physical and they are decided by tight margins."
Jenkins will line up against Ireland for the 12th time during his 113-cap Wales career on Saturday, having featured on the losing team eight times.
"It's a must-win game for us if we want any chance of winning the championship after starting slowly against England," he added.
"We have improved over the last two games (against Scotland and France), and we don't need to build this game up. We know how big it is, and we are doing all we can to get a good performance.
"You can't give too many penalties away with Johnny Sexton in the (Ireland) team. He's a world-class kicker.
"That's the same as us. Leigh (Halfpenny) bangs them over from everywhere as well.
"Discipline will be talked about, but we have to concentrate on our own game and make sure we impose ourselves on them."
