Ahead of facing his Reds colleague, the full-back said: "Florian's a top player. There's a reason we bought him for the money we did. He's obviously had a brilliant few years at Leverkusen, and now he's come to us, and I think he started the season really well. He's really good with the ball, he's really creative, and he's not scared to take a few risks with the ball as well. He's a top player and I know it's going to be a difficult night for me, but hopefully I can make it a difficult night for him too."
