With Ireland and Scotland clashing in their Rugby World Cup opener in Japan on Sunday, we take a look at some of the best matches between their domestic sides in European competition. 1997: Glasgow 30 Ulster Rugby 15 Glasgow secured a quarter-final play-off spot with this convincing success over Ulster, becoming the first Scottish side to reach the knockout stages of the European Cup. Ulster fly-half Stuart Laing kept the visitors in the match throughout with five penalty kicks, but the Irish province failed to create enough try-scoring chances to threaten the home side at Scotstoun. Glasgow were first awarded a penalty try, before scrum-half Fraser Stott and fly-half Tommy Hayes grabbed tries before the interval to create what turned out to be an unassailable lead. 2012: Ulster Rugby 22 Edinburgh Rugby 19 Ulster had to dig deep to clinch their place in the European Cup final, after a determined Edinburgh side pushed them all the way at the Aviva Stadium in Dublin. South African scrum-half Ruan Pienaar kicked the first of five penalties to put Ulster ahead, but Edinburgh No.9 Greig Laidlaw hit back with interest to give Edinburgh a 6-3 lead. Flanker Pedrie Wannenburg then restored Ulster's lead with the first try of the match as Edinburgh failed to convert any of their try-scoring chances before the interval. Two more simple penalty kicks from Laidlaw cut Ulster's lead, but nine further points from the boot of Pienaar sealed their victory despite full-back Jim Thompson's consolation try. https://twitter.com/btsportrugby/status/1111999134175805440?s=20 2019: Edinburgh Rugby 13 Munster Rugby 17 Munster Rugby sealed a 14th European Cup semi-final by defeating Edinburgh in a thrilling Heineken Champions Cup quarter-final at BT Murrayfield in front of a record last-eight crowd in the UK. Two tries from 31-year-old Ireland wing Keith Earls proved to be the difference between the two sides in a clash that made for compulsive viewing for the neutral in the Scottish capital. Centre Chris Dean grabbed a first-half try for the Scottish team, but they fell agonisingly short, despite a further eight points from the boot of fly-half Jaco van der Walt.
