We continue our guide to the 2019/20 Heineken Champions Cup with a look at Pool 4, including defending champions Saracens, two-time winners Munster Rugby and dual finalists Racing 92. Munster Rugby Ground: Thomond Park, Limerick, Republic of Ireland. European Cup record: The Irish province have two European Cups to their name, lifting the trophy in 2006 and 2008 with final victories over Biarritz Olympique and Toulouse respectively. Since then, they have reached seven semi-finals but have been beaten in each one. Last season: They were again beaten at the last-four stage. After heading a tough pool including Exeter Chiefs, they defeated Edinburgh Rugby 17-13 in the quarter-finals at BT Murrayfield, before losing 32-16 to eventual winners Saracens in Coventry. Head coach: Johann van Graan has been in charge at Munster since November 2017, taking over from Rassie Erasmus, who left to join South Africa’s national team.

New signings: Munster have promoted several players into the first-team squad from their academy and have also added Leinster Rugby scrum-half Nick McCarthy. Ospreys Ground: Liberty Stadium, Swansea, Wales. European Cup record: The Welsh region made three consecutive European Cup quarter-finals between 2008 and 2010 but were beaten in all of them by Saracens (19-10), Munster (43-9) and Biarritz Olympique (29-28) respectively. Last season: Ospreys managed to finish second in Challenge Cup Pool 2 despite winning just two of their six matches. However, it wasn’t enough to clinch a spot in the last eight as one of three best runners-up. Head coach: Allen Clarke was initially made forwards coach in 2017, before taking over as head coach on an interim basis in January 2018. He has since been made head coach on a permanent basis, signing a three-year contract until April 2021.
