We close our previews of every Challenge Cup pool today with an in-depth look at Pool 5, which consists of double winners Cardiff Blues, debutants Leicester Tigers, 2000 champions Pau and Italian side Rugby Calvisano. Cardiff Blues Ground: Cardiff Arms Park, Cardiff, Wales. Challenge Cup record: Cardiff have played only five seasons in the competition but have won the trophy twice – on their debut in 2009/10, when they defeated RC Toulon 28-21 in Marseille (the location for the 2020 final), and then again last year, when they pipped Gloucester Rugby 31-30 in a Bilbao thriller. Last season: Cardiff finished third in Pool 3 of the Heineken Champions Cup, winning only two of their six matches. Head coach: Australian John Mulvihill took over the Cardiff hot seat at the start of last season, having previously coached in his home country and Japan. New signings: Wing Josh Adams, an important member of Wales’ Grand Slam-winning side this year, has arrived from Worcester Warriors and is joined by fellow Welsh internationals Hallam Amos and Rory Thornton, who will strengthen the backs and forwards respectively. Leicester Tigers Ground: Welford Road, Leicester, England. Challenge Cup record: This will be Leicester’s first appearance in the competition. Previously, they have played in 22 European Cups, winning the trophy twice – in 2001 and 2002. Last season: Leicester were bottom of Pool 4 in the Heineken Champions Cup, after notching a solitary victory from their six games. Head coach: Geordan Murphy, Leicester’s leading European Cup try-scorer with 25 in 74 games and a member of both their European Cup-winning sides, was made interim head coach in September 2018 after the departure of Matt O’Connor and was handed the permanent job last December. New signings: After Leicester’s disappointing campaign last term, there have been a host of departures and arrivals at Welford Road, with the best-known signing probably being 52-cap Argentina lock Tomas Lavanini. The Tigers have also signed two international centres in South African Jaco Taute and Irishman Noel Reid, as well as ex-Samoa prop Nephi Leatigaga. Pau Ground: Stade du Hameau, Pau, France. Challenge Cup record: Pau have reached the final twice – in 1999/2000 and 2004/05 - winning the first 34-21 against Castres Olympique in Toulouse but losing the second 27-3 to Sale Sharks in Oxford. Last season: Pau came third in Pool 2, after winning three and losing three of their six fixtures to chalk up 13 points. Head coaches: Following the resignation of Simon Mannix last season, Pau have joint head coaches in Nicolas Godignon and Fred Manca, who took charge after Mannix’s departure. New signings: Back Ben Smith, a member of New Zealand’s 2015 World Cup-winning side and scorer of 33 tries in 78 Tests, is Pau’s big-name signing for next season. He is joined by fellow All Black Luke Whitelock, a versatile forward, plus experienced Fijian international forward Dominiko Waqaniburotu. Rugby Calvisano Ground: Stadio San Michele, Calvisano, Italy. Challenge Cup record: This will be the Brescia team’s first appearance in the competition since 2015/16, when they came bottom of Pool 3 after losing all six games. Their most successful season was in 2007/08, when they won two pool matches – against Dax and Leeds Carnegie. Last season: The Italian side topped Continental Shield Pool A with 15 points from four matches to enter the qualification play-off phase. In that they saw off Rovigo Delta 57-43 over two legs to clinch a spot in the Challenge Cup. Head coach: Massimo Brunello has been in charge since 2015, arriving from the Italian Federation, where he managed the national under-17 and under-18 teams. He won the first championship of his coaching career in 2017. Leading players: Calvisano will probably look to the experience of Fijian-born No.8 Samu Vunisa and scrum-half Fabio Semenzato to spearhead their Challenge Cup campaign. Both have played Test rugby for Italy – as has prop Matteo Zanusso.
