This week we take an in-depth look at Ospreys, who are set to play in the Challenge Cup for just the second time – in Pool 2 alongside Pau, Stade Français Paris and Worcester Warriors. What is their Challenge Cup record like? The Welsh region have only played in the Challenge Cup once, in 2016/17. They sailed through the Pool stages, winning every match in Pool 2 before a quarter-final defeat to eventual winners Stade Français Paris. Who is on their coaching staff? Allen Clarke was appointed head coach in April after three months as interim head coach, having joined the Welsh region last summer as forwards coach under Steve Tandy. His coaches include Matt Sherratt (backs), Brad Davis (defence) – who has previously coached at Bath Rugby – and former Wales prop Duncan Jones (skills). Who are their principal new signings? Ospreys have made a number of eye-catching signings during the off-season, with Wales wing George North the most noteworthy after joining from Northampton Saints. The 26-year-old British and Irish Lion has scored 10 tries in 36 European appearances. Other additions include Wales duo Aled Davies and Scott Williams, former Cheetahs prop Tom Botha and Namibia centre Lesley Klim. https://twitter.com/ospreys/status/1009466091184316418 Who are some of their other key players? Wales lock and captain Alun Wyn Jones leads a wealth of international talent, including Wales flanker Justin Tipuric and fly-half Sam Davies, Moldova prop Gheorge Gajion and Georgia lock Giorgi Nemsadze. What are Ospreys saying about the draw? Allen Clarke told Ospreys' website: "It’s a really exciting draw. We are pooled with three teams that have real quality right the way through and will provide different challenges to what we are used to week in, week out, in the PRO14. “When you look at our Pool, and the list of teams in the competition this year, it’s an indication of how the game is growing in Europe and the challenge that teams face across their domestic leagues to qualify for the Champions Cup. “Pau showed their quality in this competition last season, winning their Pool unbeaten, defeating Gloucester and going through to the semi-finals, where they pushed the Blues all the way in Cardiff. “Stade are one of the traditional giants of French rugby and are approaching next season with a renewed vigour, so will be a really dangerous outfit with real quality. "Worcester are a club that have invested and recruited, so will have increased expectations for the coming season. I know some of the coaching staff and we’ll see Ashley Beck coming back to the Liberty, which will give it an added dimension."
