Roma and/or Spurs should hold their heads in shame if they fail to meet each other in the final.
Edit: just noticed Rennes also managed to qualify. They're also potential finalists and will be aiming to, at the very least, reach the semi-finals.
Below that you have the likes of Feyenoord, AZ Alkmaar, Union Berlin, Slavia Praha, KAA Gent, and PAOK who'll be aiming for the quarter finals.
Also wouldn't exclude LASK or FC København from causing upsets in the KO stages.
