England coach Eddie Jones says he will continue to pick the best available players and doesn't care how long they've been in the country.
Jones made a statement after World Rugby increased the residency qualification period from three to five years, effective from late 2020. But there was no change to the grandparent rule which is how 30-year-old New Zealander Willi Heinz has qualified for the England squad.
The former Crusaders halfback is the latest to appear on Jones' radar after being added to the 26-man camp earlier this week which is part of England's preparations for a two-test tour of Argentina next month.
"It's not my job to worry about how they qualify, it's my job to pick players that qualify," Jones told the Press Association.
"I don't care how they qualify, I'll pick them. That's the rules we play under. I obey them like any good schoolteacher does."
