Rookie centres Ollie Lawrence and Cameron Redpath will start for England and Scotland respectively in Saturday’s Calcutta Cup clash at Twickenham.
Lawrence and Redpath go head to head, having played in the same midfield for England Under-20s in 2019.
But Redpath isn’t the only former England U20 star who will be playing for a different country in the 2021 Six Nations.
1. Ross Moriarty (Wales)
The hulking back-rower, whose father is former Wales international Paul Moriarty, initially played for England at both U18 and U20 level, winning the IRB Junior World Championship in 2014. However, he has since made his full international debut for Wales and has since won 44 caps while also representing the British & Irish Lions during their tour of New Zealand in 2017.
