Completely agree with Zenit, top of the Russian league and should have way too much for the part-timers who have racked up a few decent results but this is a much harder test than anything they've faced before. -1 at 10/11 (Coral, Paddy, Ladbrokes) also looks good.
Two other prices stuck out for me:
Flying high at top of Romanian league, Steaua Bucharest at home to FC Zurich (who play in the Swiss 2nd tier) is 10/11 (WHills) which almost seems too good to be true. I haven't checked team news yet though.
Man Utd should cope comfortably with Fenerbache, I think 8/13 (Betfred) for the home win is decent value. United aren't exactly setting the heather alight so far this season, but Fener are doing pretty badly - 9 points from 7 opening league games in a far inferior league. Niggling doubt would be what team Mourinho sends out in a competition he obviously doesn't care an awful lot about.
