Leinster coach Leo Cullen to leave after 2026-27 season

Leinster head coach Leo Cullen will depart the Irish province at the conclusion of the 2026-27 season, the club confirmed this week. Cullen, who has led the team since 2015, announced his decision on Monday, stating that after 12 years in the role, the timing is right for a new challenge.

The announcement immediately triggered a formal recruitment process, conducted in collaboration with the Irish Rugby Football Union, to find his successor. The future of senior coach Jacques Nienaber, whose contract expires concurrently with Cullen's, has become a central topic of speculation. Nienaber, the former South Africa head coach who joined Leinster after the 2023 Rugby World Cup, recently expressed doubts about his standing, stating he did not feel valued in Ireland.

Cullen's tenure has been marked by consistent domestic success, including a sixth United Rugby Championship title secured last Friday with a comprehensive win over the Bulls in Dublin. However, the club's inability to add to its 2018 European Champions Cup title has drawn scrutiny, with Leinster losing five finals since, including a 22-point defeat to Bordeaux-Bègles last month.

Opinions differ on Nienaber's potential...
