Levski Sofia are seen as odds-on favourites to win this clash following heavy summer recruitment, but Sarajevo are also hoping for a good result in the first leg.
PFC Levski Sofia are by far the most decorated club in Bulgaria, although they have failed to win the league title in the last three attempts.
The Blues finished last season in third place, eight points behind champions Ludogorets, but they have since seriously reinforced the squad.
In came Stanislav Angelov, Agyemang Opoku, Basile de Carvalho, Romain Elie, Roman Prochazka, Marcinho and Joao Silva, and there are no doubts the squad are now much stronger than last term.
Even though new boss Ilian Iliev will need some time to get the team playing like they should, you should know home win pays 1.44 (4/9) at Stan James.
New signing from Everton Joao Silva still lacks match practice and is unlikely to start, but all other players are ready for the Sarajevo game.
Probable starting line-up (4-3-3): P. Iliev – Mulder, Ivanov, Elie, Starokin – Prochazka, Angelov, Gadzhev – Marcinho, De Carvalho, Raykov.
Sarajevo, one of the two most famous clubs in Bosnia, have been on the downtrend of late and their fourth-place finish last season was hardly seen as a major achievement.
They, nonetheless, managed to beat Olimpic to the final Europa League berth, although the draw was a bit harsh on them.
FKS enter the new season with a severely changed squad, but they don’t look much stronger than last term.
Despite the arrival of Tadejevic, Gujic and Tatomirovic, the back line remains extremely shaky, but in Husejinovic, Suljic, Haskic and Karamatic they’ve got plenty of quality options in attack.
Given there were no less than 15 goals scored in their two matches against Hibernians from Malta, odds of 2.80 (9/5) offered by Sportingbet on over 3.5 goals look too good to pass.
Probable starting line-up (4-4-2): Adilovic – Gujic, Torlak, Tatomirovic, Belosevic – Husejinovic, Comor, Sesar, Zlatkovic – Suljic, Hadzic.
