#2 James Rodriguez vs Toni Kroos
The UEFA Champions League has a history of loanees come back to haunt their parent clubs (see Morientes, Fernando) and James Rodriguez will look to become the latest addition to that list. Playing in a deep-lying playmaker role, James played with the kind of defensive discipline and diligence that Zinedine Zidane apparently thought he lacked during his time at Madrid, and he was a real presence offensively and defensively.
Up against him that night, standing toe-to-toe and playing a touch higher up than we're used to seeing him, was former Bayern darling, Toni Kroos. Sold for a paltry sum of €25 million - and two years of Xabi Alonso - by his first major club, the German has nursed this for quite some time now and generally ends up bringing his A-game to any match against Bayern.
He'll need to be at it again to stop James pulling the strings from deep; while the Colombian, in turn, will have to do likewise to stop Kroos from running the game.
