Munster Rugby head coach Johann van Graan believes it will be a “massive challenge” to get out of Heineken Champions Cup Pool 4, after being drawn with defending champions Saracens, 2018 finalists Racing 92 and Ospreys. “This pool is full of top-quality sides and it will be a massive challenge,” the South African, whose side were beaten by Saracens in the semi-finals last season, told the Munster website. “Saracens have just completed the double after winning the Champions Cup and the Premiership, and everyone knows how strong they are. “Munster and Racing have faced each other quite a few times in recent years. They are a side that have so many talented players in every position and have reached the final of the competition twice in the last four seasons.” https://twitter.com/ChampionsCup/status/1141679597769166848 And while European heavyweights Racing 92 and Saracens look like the chief opposition on paper, Van Graan also highlighted the threat of Welsh region Ospreys. He added: “Ospreys are another quality outfit we know really well from the PRO14. They won more games than any other Welsh side in the league last year and showed how much the Champions Cup means to them with their excellent play-off win over Scarlets last month. “It’s such a tough draw, but that’s why it’s called the Champions Cup and that’s why we want to be in this competition. “It will be a very exciting challenge for us and it is one that we are looking forward to.”
