With the Heineken Champions Cup getting underway next month, we look at four clashes that you simply cannot afford to miss in Round 1! Pool 5: Gloucester Rugby v Toulouse The 2019/20 Heineken Champions Cup gets under way with a cracking Friday night clash between double Challenge Cup champions Gloucester and four-time European Cup winners Toulouse at Kingsholm Stadium on November 15. The visitors enjoyed an excellent 2018/19 campaign, winning five pool matches before defeating Racing 92 22-21 in the last eight. They lost to Leinster Rugby in the semi-finals but did win the TOP 14 for a 20th time after a 24-18 victory over ASM Clermont Auvergne in the final. Gloucester could only manage two wins in the competition last season but have decent pedigree in the Challenge Cup, having reached the final three times in the last five years, and so will be seeking to transfer that to the top tier. You can tune into this clash on BT Sport and beIN SPORTS, with the action getting under way at 19:45 GMT. Pool 3: Bath Rugby v Ulster Rugby Bath will kick off their 2019/20 European adventure with the visit of last season's quarter-finalists to the Recreation Ground on November 16. The English club, who were European Cup champions in 1998, are looking to reach the knockout stages of the competition for the first time in five years. Ulster had an excellent Heineken Champions Cup campaign last season, reaching the last eight after registering five pool wins, but they then lost 21-18 to fellow Irish province Leinster Rugby in a closely-fought quarter-final at the Aviva Stadium. The Belfast-based club have the upper hand on Bath in the head-to-head stakes, winning all four of their previous encounters in Europe. You can catch this Pool 3 game at 13:00 GMT on Channel 4, Virgin Sports, beIN SPORTS and BT Sport. https://twitter.com/ChampionsCup/status/1164824951741767681 Pool 2: La Rochelle v Exeter Chiefs 2019 Challenge Cup finalists La Rochelle move back up to the Heineken Champions Cup for the 2019/20 campaign and take on Gallagher Premiership runners-up Exeter Chiefs in their opening Pool 2 clash on November 16. The French club made a splash in their maiden Champions Cup season in 2017/18, topping Pool 1 before falling in the last eight to Scarlets in a 29-17 defeat at Parc y Scarlets. Exeter have only once made it out of the pool stages. Last season they narrowly missed out, a 9-7 loss to Munster Rugby in Round 6 eliminating the Sandy Park side. BT Sport and beIN SPORTS will have live coverage of this game at the Stade Marcel Deflandre from 15:15 GMT. Pool 4: Racing 92 v Saracens A repeat of the 2016 Champions Cup final, Racing 92 will be looking to avenge that 21-9 defeat to defending champions Saracens when they meet at the Paris La Defense Arena on November 17 in the final match of Round 1. Saracens’ recent European pedigree is outstanding. They won their third Champions Cup in four seasons in May when rallying from 10-0 down to defeat defending champions Leinster Rugby 20-10 in the showpiece final at St James’ Park, Newcastle. Since being losing finalists in Saracens’ first Champions Cup success, Racing have reached the 2018 final, but were also edged out then, falling 15-12 to Leinster in a tense clash at the San Mames Stadium in Bilbao. You will be able to watch this game in the UK on BT Sport, with coverage in France on France Television and beIN SPORTS from 15:15 GMT.
