Record five-time winners Toulouse held off a second-half fightback from Harlequins to win a pulsating home Champions Cup semi-final 38-26 on Sunday and set a date with Leinster in the decider at the Tottenham Hotspur Stadium on May 25.

Scrumhalf Antoine Dupont scored a brace of tries as the French side ran in six scores in all, five of them in a dominant first half that gave them a 31-12 lead at the break.
