All to play for in Athens after a goalless first leg, and that leaves AEK in the driving seat as 1/21.50 favourites, while Levski Sofia are big 5/16.00 underdogs in the 90 minutes.
The Greeks were rusty in Bulgaria and that looks a big missed chance for Levski, as AEK won 4-0 on Saturday so look to be finding their feet - they've also won eight of 11 at home and lost just once in 10 European home games.
Levski enjoyed a thumping 6-0 win though so this should be the exact opposite of the first leg. Expect Sofia to score but I can't see them beating the Greeks.
Back AEK to win and both teams to score
Celje are 5/42.25 match favourites here to become just the second Slovenian side to make the Champions League group phase, with Yaya Toure's Slovan Bratislava 2/13.00. Toure is unbeaten in nine as the team's manager with five clean sheets in his seven wins.
Again both sides come with goals - seven of Celje's nine games this season saw both teams score along with eight of 12 home games in Europe, while Slovan have scored 2+ goals in eight of their past 10 games on the road. But the odds are decent enough here to roll with Yaya's boys to get the job done.

First Leg: 1-1

Advantage Lyon after a draw in Turkey, with the hosts 4/51.80 match favourites with seven wins in 10 European home games, while they've progressed from five of six Champions League qualifiers. Fenerbahce are 14/53.80 as although there's plenty of big names they've lost all nine qualifiers since their last UCL group stage appearance in 2008.
All five Fenerbahce qualifiers have gone under 2.5 goals and it'll be a similar approach here, but despite having new signing Romelu Lukaku I think Lyon will just pip them - and that will likely mean the visitors drawing a blank.
Viking battled back from 2-0 down to draw the first leg in Croatia, and the Norwegians are 6/52.20 match favourites, but history isn't on their side as they've lost all seven Champions League play-off ties and won just one of those 15 matches.
So 13/82.63 Dinamo will still fancy their chances as a more experienced European side with seven wins from 10 UCL play-offs, but they my need to score a couple as they've managed just one away clean sheet in seven. So although I can't quite call this one there's high confidence in there being a good few goals.
