Jimmy Gopperth’s touchline conversion of Charles Piutau’s try scored with four seconds remaining completed a 13-point comeback and assured Wasps’ passage into the Champions Cup semi-finals for the first time in nine years.
After their driving lineout had foundered on the rock of Exeter’s defence, Wasps spun the ball right, Elliot Daly feeding Piutau running the most gorgeous of angles.
