After last month’s Heineken Champions Cup Pool Draw in Lausanne, we take a closer look at Pool 4, including last year’s Champions Cup semi-finalists and finalists, as well as a back-to-back European Cup winner. Leicester Tigers Ground: Welford Road, Leicester, England. European Cup record: Leicester lifted Europe’s elite club trophy in successive seasons – 2001 and 2002. In 2001 they recorded a thrilling 34-30 final victory over Stade Français Paris at Parc des Princes in the French capital and they repeated the trick 12 months later after a similarly tense final in Cardiff, where they were 15-9 victors over Munster Rugby. Last season: They didn’t reach the heights that they would have liked to in last season's competition, finishing fourth in Pool 4, which also contained eventual semi-finalists Munster Rugby, finalists Racing 92 and TOP 14 winners Castres Olympique. Head coach: Australia international Matt O'Connor is at the helm after joining the club for a second time in March 2017. He had previously spent time at Queensland Reds and Leinster Rugby. Key players: Leicester can boast plenty of England internationals, including scrum-half Ben Youngs, fly-half George Ford and wing Jonny May. Amongst others they have added back-row forwards David Denton and Guy Thompson, plus Argentina prop Gaston Cortes, to their squad in the off season. https://twitter.com/racing92/status/1009432760728027137 Racing 92 Ground: U Arena, Paris, France. European Cup record: Racing 92 are now two-time European Cup runners-up after defeats in the 2016 and 2018 finals. In 2016 they suffered a 21-9 reversal in Lyon to Saracens and then earlier this year went down 15-12 to Leinster Rugby in Bilbao. Last season: The Parisian club finished behind Munster Rugby in Pool 4 but defeated them 27-22 in the semi-finals after a majestic first-half performance from wing Teddy Thomas. However, they fell agonisingly short against Leinster in the final. They also came second in the TOP 14. Head coach: Racing 92 are coached by Laurent Labit and Laurent Travers, with the duo joining in 2013. They enjoyed previous success together at Montauban and Castres Olympique. Former Racing wing Chris Masoe was added to the coaching staff last season as defence coach. Key players: The TOP 14 team have increased their talent pool during the off-season by signing Scotland fly-half Finn Russell, Irish international wing Simon Zebo and Fiji utility back Ben Volavola. They join the likes of Thomas, centre Virimi Vakatawa and EPCR European Player of the Year 2018 Leone Nakarawa at the U Arena. Scarlets Ground: Parc y Scarlets, Llanelli, Wales. European Cup record: Scarlets have reached two European Cup semi-finals – in 2007 and 2018. In 2007 they lost 33-17 to Leicester Tigers, while last season they succumbed 38-16 to Leinster Rugby. Last season: They topped Pool 5 and then defeated La Rochelle 30-19 in the quarter-finals in front of a record European Cup crowd at Parc y Scarlets, before falling short in the semi-final. Head coach: Wayne Pivac has one more season in charge of Scarlets before departing to become Wales’ head coach following five years with the Welsh region. Pivac guided Scarlets to a first PRO14 title in 2017 after a 46-22 victory over Munster in the Dublin final. Key players: Scarlets have a nucleus of Welsh international talent, including hooker Ken Owens, scrum-half Gareth Davies, fly-half Rhys Patchell and full-back Leigh Halfpenny. https://twitter.com/UlsterRugby/status/1017038499013451776 Ulster Rugby Ground: Kingspan Stadium, Belfast, Northern Ireland. European Cup record: The Irish province won Europe's elite club competition in 1999 after a 21-6 victory over Colomiers in the final in Dublin, with full-back Simon Mason kicking 18 of their points. They also reached the final in 2012 but were beaten 42-14 by Leinster Rugby at Twickenham. Last season: Ulster finished third in Pool 1 despite winning four matches and collecting 17 points. They secured the final PRO14 qualifying place for next season’s Heineken Champions Cup with a 35-17 victory over Ospreys. Leadership: Ireland coach Simon Easterby will provide coaching support at Ulster in the interim period before the arrival of new head coach Dan McFarland. Key players: Ulster have added Leinster Rugby back-row forward Jordi Murphy and Gloucester Rugby fly-half Billy Burns to their squad, joining the likes of Ireland wing Jacob Stockdale and hooker Rory Best at the Kingspan Stadium.
