As the two French rivals prepare to go head-to-head in the UWCL semi-finals this weekend, with the winner to face Barcelona or Chelsea in May's final, PSG star Groenen has reflected on what makes it so tough to beat Lyon.
"They have a lot of quality. That's the first point," she said. "That's honestly why it makes it hard to play them because they have a lot of different styles that they play, with different styles of players. They've got a lot of different qualities, which makes it less obvious how to defend the different styles of attacking, and they're just physically very strong as well.
"I think that's something that we had to work on. They're a big team, they're a good team, but we're trying to get there too. I think there's been such a progression that I'm very curious about the game. I'm very excited because I think we can [beat them]. At the moment, I think we can and that's something everyone feels. But you know how it is with rivalries, it's never easy."
Asked how much of the game is about mentality too, where Lyon have an edge given their dominance, Groenen said: "It's obviously a huge part because if you have the experience of winning, it's something that counts as well on the pitch. I think that's something that we've been working on this year and I think that's also something that you could see in the last game [a 1-1 draw in February], so we try to work from there. I think with the qualities we have now, we will be able to beat anyone if we manage to play our own game."
