#2. England: Twickenham
Care: “Twickenham is the home of rugby. I remember the first time I ran out I was like ‘wow, this is cool’ and I had tears in my eyes.
“When it’s loud it’s as good as any other Six Nations stadium, but when it’s quiet and you’re not playing well you know it as an England player – and you feel it.
“I’ll always remember we played Argentina [in 2009] and the biggest cheer of the day was when somebody threw a paper airplane and it went through the posts because we were playing that badly.”
Warburton: “I loved the way the bus would come in. You go through a few high streets and you can see people in the pubs in England shirts and the bus pulls up about 100 metres away from the stadium.
“It was quite hostile but I loved it, that’s what it’s all about. We’re like the small brother coming across the Severn Bridge and that’s when I really felt the rivalry. I did find if we were winning it would go very quiet so it was a massive thing to silence the crowd.”
#1. Wales: Principality
Warburton: “[It’s] the proximity to the pitch and how close the fans are to the action. We had to have body language [line-out] calls because we couldn’t physically hear each other.
“It’s in the city centre and if you’re not in the stadium there’s another 100,000 people drinking within a half a mile radius of the stadium.
“It’s just the hub of Cardiff. Location-wise, it’s definitely the best. I always think ‘oh, am I being biased?’ But even [former New Zealand captain] Richie McCaw said you haven’t completed your international graduation unless you’ve played at the Principality.”
Care: “This is why I love the Principality: genuinely you will see 90-year-old women sticking two fingers up against the bus as you drive through the city centre.
“There was a guy with all the face paint on and he ran and genuinely headbutted the bus! That has always stuck with me, how passionate that guy was. I think it was quite early on in my England days and that was the first time one of the senior players said, ‘lads, you’ll want to take your headphones off and listen to this.'”
