Bayer 04 Leverkusen - FC Zenit St. Petersburg:
Bayer Leverkusen are strong at home, they'll most likely win the first leg over Zenit. The second leg will be a lot harder though and it's really hard to predict the outcome of that game, especially when Zenit are in form after their league started.
3-0 Second leg:
FC Bayern München - Getafe CF:
Bayern are major favourites in this one, they'll most likely advance to the next round if they get a good result at home. They should however look out for Getafe, they're tricky to play and it wouldn't surprise me if they continued to surprise Europe.
In terms of quality and experience though, Bayern should be superior, but you never know with Getafe, they're pretty much unpredictable.
2-0 Second leg:
Glasgow Rangers FC - Sporting Clube de Portugal:
Rangers are favourites at home but they'll have to get a good result from the first leg, they'll struggle otherwise. I think Sporting will get a pretty good result from the first leg, perhaps a draw, wouldn't surprise me anyways.
Will hopefully be a well fought game.
1-1 Second leg:
ACF Fiorentina - PSV Eindhoven:
This game is the most interesting in my oppinion, Fiorentina are really strong at home and PSV will look to get a decent result to Eindhoven, really hard to predict the outcome IMO.
The team that gets best result away from home will most likely go through. Could be another game to decide on penalties..
