Harsh lessons for Leinster in shock defeat

The Irish province came close to earning a losing bonus point after attempting a late fightback in a tie that had swung away from them after the break.
Leading 22-12 early in the second-half Leinster fell asleep at the wheel and allowed Glasgow wing Tommy Seymour to score twice under the posts in the space of five minutes. Seymour went on to complete a second-half hat-trick and left the visitors with plenty of food for thought.
