The Munster loose forward said he appreciates the significance of helping Ireland chase just a third Six Nations clean sweep, especially on St Patrick’s Day and at Twickenham.
Ireland claimed a record 11th consecutive win, as they overcame Scotland by 28-8 on Saturday. It proved enough to swipe the title a week early, as England lost 22-16 to France in Paris.
Former South Africa Under-20s star Stander swapped Super Rugby’s Blue Bulls for Munster in 2012, after Springboks coaches told him he was too small to be a Test-match flanker.
Six years on, he has a British and Irish Lions cap, helped Ireland claim a first win over New Zealand, and can now drive Joe Schmidt’s men to a first Grand Slam since 2009.
Asked if Saturday’s Twickenham showdown is the biggest game of his career, Stander replied: “Yes, for sure; there’s an opportunity to create something for ourselves as a group.
“Some of us, it’s their first Six Nations, some of us have been here for a few years.
“Preparation wise, put the head down, make sure you train well and get into the team for Saturday.
“It’s a great opportunity. You set goals for yourself at the beginning of the year and, on a personal level, you strive to be part of that.
“Now we’ve got an opportunity and we’ve got to make sure we rest up and get ready for next week.
We’ve talked to players and ex-players who won the Grand Slam. This group, we haven’t had the opportunity, so we can look back at how they did it and what it meant to them. We’ve still got a job to do.
Allied to setting a new all-time national win record, Kiwi coach Schmidt has now guided Ireland to three Six Nations titles in just five years.
Stander has become an Ireland mainstay under Schmidt since qualifying on residency and making his debut in the 2016 Six Nations.
The 27-year-old has always spoken candidly about his decision not to accept the Springboks’ attempts to convert him into a hooker, believing him too small to cope as a Test back-row forward.
Now, however, with 22 Ireland caps under his belt in the back-row, Stander feels his decision more vindicated than ever, though he knows some may never agree.
Asked if opportunities like chasing a Grand Slam with Ireland only serve to add more credence to his original decision to leave South Africa, Stander said: “Yes, but at the same time a lot of players make a lot of sacrifices.
“I’ve made a lot of sacrifices to be here, but a lot of people stuck their head out for me and taught me a lot of the game.
“I lost a lot of friends and coaches along the way, so it’s good to give them something back.
We said as a group we wanted to achieve something. That was probably in the back of our minds. We’ve played well in the last few games, got lucky as well in a few games.
“Some games we were physically dominant. It’s a great achievement for this group and hopefully we can push on.”
