**Leinster head coach Leo Cullen hailed a “massive squad effort” after seeing his invincible side lift the Guinness PRO14 trophy for a third straight year.** Cullen’s side fell behind early against Ulster in Saturday’s Final but were 10-5 up by half-time courtesy of James Lowe’s converted try and a Ross Byrne penalty. Byrne added another penalty after the break before further scores from Robbie Henshaw and Caelan Doris helped seal a remarkable hat-trick of titles for a Leinster side who have won every Guinness PRO14 match they have played in the 2019/20 season. The depth of talent within the squad is reflected by their use of 53 players throughout the campaign – a point not lost on Cullen as he reflected on the province’s latest triumph. “A huge effort has gone into this campaign,” he said. “If you think back to when we started, in the middle of the World Cup, we were missing so many players. World Cup years are very tricky years so huge credit goes to all the squad as a massive effort went in to get us to this point.
