Former England and British & Irish Lions prop Mako Vunipola says he is targeting a coaching role with Tonga for the 2027 Rugby World Cup, while younger brother Billy Vunipola could still feature as a player under eligibility rules.

Tongan rugby officials have reportedly approached both brothers about potential involvement ahead of the tournament in Australia. World Rugby regulations allow players to switch national teams after a three-year stand-down period, leaving open the possibility of Billy representing his ancestral nation.

Mako, currently with Saracens, confirmed the 2024–25 season will be his final year as a professional player. Speaking to RugbyPass, he said he intends to transition fully into coaching and would welcome the chance to support Tonga’s national programme.

He said the physical demands of elite rugby made playing through to 2027 unlikely, noting that training and preparation place as much strain on the body as matches themselves. While he had discussed the possibility of representing Tonga on the field, the timing no longer aligned with his career plans.

Mako added that contributing as a coach would be “very special”, highlighting pride in his Tongan heritage and a long history of supporting Billy’s development throughout their careers.

Tonga continues to explore pathways to strengthen its squad and coaching structure ahead of 2027, with eligibility reforms and diaspora talent expected to shape preparations in the coming years.
