The tie will see Bradley face new Liverpool teammate Florian Wirtz.
"Florian's a top player. There's a reason we bought him for the money we did," said Bradley.
"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."
Bradley added, "It's going to be a really difficult test. Germany are one of the top nations in the whole world.
"They've got some top players, so it's always nice going up against top players and seeing where you're at compared to them.
"Obviously with the result the other night for them, they're going to be bang at it from the start so we've got to stick together and I think we're in with a good chance."
