The Gallagher Premiership side were drawn into Pool 2 during Wednesday’s pool draw, and will come up against Stade Toulousain, Cardiff Rugby, Racing 92 and Ulster Rugby.

Domestic rivals Bath Rugby also feature in the pool, but Quins won’t be pitted against them – as per the competition’s new format – when the fixtures are confirmed in due course.

Quins have played Racing in two of the previous three pool stages and faced off with Cardiff in the 2021/22 campaign.

Millard wasn't surprised by the quality of Quins’ opposition and implored his player to stick to the basics when the tournament kicks off on December 8/9/10.

“I guess we knew that it was going to be [tough], whichever way it went,” he told Quins’ website. “It’s the Champions Cup for a reason.

“But we’ve got history with all the teams. We’ve got recent experience with Cardiff and Racing, a good history with Toulouse and Ulster we know pretty well.

“It’s going to have its challenges, as all the games in the Champions Cup do have. I think the next element is the home and away element, when that’s announced. That’ll help our approach to it.

“You just have to win your games. We’ve shown that we’re very capable of beating the big teams at home and we’ve very capable of beating them away.

“I think if can go into it with too much formula. You’ve just got to win each game that comes at you and each one provides a different challenge.”

Harlequins director of rugby Billy Millard challenged his team to take each game as it comes in the 2023/24 Champions Cup pool stage after they were drawn against some familiar foes.
