After last month's Heineken Champions Cup Pool Draw in Lausanne, we take a closer look at Pool 2, including last year's Challenge Cup finalists and a 13-time European Cup semi-finalist. Exeter Chiefs Ground: Sandy Park, Exeter, England. European Cup record: Exeter have only made it out of the European Cup Pool stages once, in 2016. They were denied a spot in the last four, though, after a late Jimmy Gopperth conversion saw the Devon club lose 25-24 to Wasps. Last season: Exeter finished second behind eventual winners Leinster Rugby in Pool 3, but didn't qualify for the knockout stages as one of the three best runners-up. They had more success in the Aviva Premiership, finishing top of the table before losing 27-10 in the final to Saracens. Director of rugby: Rob Baxter spent 14 years with Exeter as a player, before moving 'upstairs' as forwards coach and eventually becoming head coach in 2009 and director of rugby in 2017. He helped Exeter to promotion from the RFU Championship in 2009 and guided them to a maiden Aviva Premiership title in 2017. Key players: The Chiefs have several England internationals in their ranks, including centre Henry Slade, No.8 Sam Simmonds, wing Jack Nowell and prop Harry Williams. They have made only two new signings so far, with Wales wing Alex Cuthbert joining from Cardiff Blues and Argentina utility back Santiago Cordero from Super Rugby side Jaguares. https://twitter.com/ChampionsCup/status/1011153269110943744 Gloucester Rugby Ground: Kingsholm Stadium, Gloucester, England. European Cup record: Gloucester have not qualified for the European Cup knockout stages for over a decade, with their last quarter-final coming against Munster Rugby in 2008, when they were beaten 16-3. Last season: Gloucester reached the Challenge Cup final, but suffered a heart-breaking 31-30 defeat to Cardiff Blues, with Gareth Anscombe kicking the winning penalty in the dying seconds. They finished seventh in the Aviva Premiership, but qualified for the Heineken Champions Cup with Leinster Rugby and Cardiff having already secured berths through their league positions. Director of rugby/head coach: Former Ireland fly-half David Humphreys is the director of rugby, having joined the English club in 2014 from Ulster Rugby. Ex-South Africa lock Johan Ackermann was appointed head coach in 2017, after spending four seasons at Super Rugby side Lions. Key players: England duo Danny Cipriani and Matt Banahan moved this summer from Wasps and Bath respectively to join a host of internationals at Kingsholm. Ackermann has also added five South Africans during the off-season, including former Lions trio Jaco Kriel, lock Franco Mostert and prop Ruan Dreyer. https://twitter.com/gloucesterrugby/status/1013690510362533888 Munster Rugby Ground: Thomond Park, Limerick, Ireland. European Cup record: Two-time European Cup winners Munster Rugby have a fantastic pedigree in Europe's elite club competition, having reached 13 semi-finals from 23 competitions. They tasted victory for the first time in 2006, beating Biarritz 23-19 in the final, and notched a second success in 2008 by defeating Toulouse 16-13. Last season: Munster Rugby came through Pool 4 as winners ahead of eventual finalists Racing 92. They defeated RC Toulon 20-19 in the quarter-finals after a spectacular last-minute try from wing Andrew Conway but were beaten 27-22 by Racing 92 in the semi-finals at Stade Chaban-Delmas. Head coach: Johann van Graan took over the reins at Munster last season from Rassie Erasmus, who left his role as director of rugby to coach South Africa. Key players: Munster have a strong core of Ireland internationals, including scrum-half Conor Murray, No.8 CJ Stander and captain Peter O'Mahony. Lock Tadhg Beirne – who scored last season's Champions Cup Try of the Season – has joined Munster from fellow Champions Cup semi-finalists Scarlets, while fly-half Joey Carbery has signed from Leinster Rugby. https://twitter.com/Munsterrugby/status/1009779285542961152 Castres Olympique Ground: Stade Pierre-Fabre, Castres, France. European Cup Record: Castres have only reached the knockout stages of the European Cup on one occasion, in 2002. After defeating Montferrand 22-21 in the quarter-finals, they came unstuck against Munster Rugby in the last four, losing 25-17 in Béziers. Last season: Castres finished third in Pool 4, behind eventual semi-finalists Munster Rugby and runners-up Racing 92. In contrast, they won the TOP 14 title, despite coming sixth in the league. They defeated Montpellier 29-13 in the final. Director of rugby: Hooker Christophe Urios spent 10 years as a player with Castres, before joining the coaching staff as a forwards coach. He then had coaching roles at Bourgoin and Oyonnax, before rejoining Castres in 2015 as director of rugby. Key players: Castres boast a wealth of international talent, including France full-back Geoffrey Palis, Argentina fly-half Benjamín Urdapilleta and Tonga back-row forward Maama Vaipulu. One notable acquisition during the off-season has been ASM Clermont Auvergne full-back Scott Spedding. The 28-year-old has scored nine tries in 41 European appearances. https://twitter.com/ChampionsCup_FR/status/1011534653126332416
