Chelsea v Borussia Dortmund (20:10 GMT, 0-1 first leg)
One of Borussia Dortmund's star players is 19-year-old England midfielder Jude Bellingham, who is constantly linked with Premier League clubs.
Boss Edin Terzic said: "He had opportunities to join the Premier League but he chose to join us because he knows it can be the perfect step for him. I think we've proven it both ways. He's helping us a lot. But we as a club are helping him and his career as well.
"We are really happy that he's part of our team, he's one of our leaders at 19. But we know that we need a good performance from him on Tuesday.
"It'll be a topic for his future, but our future now is that we're going to face a really tough opponent and so we need him in a good way."
Team-mate Emre Can said: "He's a world-class talent, everybody knows his potential. Jude has to know himself what he is doing.
"It's difficult to say what is best for him. He and his family have to decide that."
