One of Europe's traditional powerhouses meets the continent's nouveau riche at the Allianz Arena on Tuesday night, in what promises to be one of the ties of the round in the Champions League.
Bayern Munich, on an impressive early-season winning streak of nine games in all competitions, face Manchester City and their wealth of newly-assembled talent.
It's a game that captures the imagination, not least because of the two clubs' form. While Bayern are blazing a trail in the Bundesliga, City have barely put a foot wrong in the Premier League and are currently second to their local rivals Manchester United only by virtue of goal difference.
Tuesday will see a galaxy of stars light up the sky in Munich, but who are likely to be the major movers and shakers?
Here we look at six players to watch.
