Borussia Dortmund: Marco Reus
Borussia Dortmund's main problem appears to be to try and keep Marco Reus fit and on the pitch.
If they do that, though, they have one of the game's finest attacking talents on their hands, a playmaker who can score and a direct runner who can attract opponents and create space for others to exploit.
Reus finished last year as one of the most in-form players in Germany, and he is more than capable of transferring that to the biggest stage this season...as long as, of course, his injuries abate.
