Home ground at Dragalevtsi provides a small edge and Draw No Bet protects against the realistic chance of a low-margin draw given both teams' defensive frailties (Septemvri conceded 63, Spartak 56).
Pick: Draw No Bet - FK Septemvri Sofia to 1.65 @ Casumo - Up to £30 Free Bet for New Players*
Both sides have high goals-against totals (63 and 56) and low clean-sheet rates (7 and 8), a profile that normally produces matches with three or more goals; this matches the market view flagged by academiadeapuestasperu.
Pick: Over 2.5 Goals to 2.35 @ Casumo - Up to £30 Free Bet for New Players*
Spartak have conceded slightly fewer goals and can exploit Septemvri's defensive lapses on breaks; an away win is plausible but risky so odds are appropriately large.
Pick: FK Spartak Varna to Win to 6 @ Casumo - Up to £30 Free Bet for New Players*
Both teams have enough scoring output (29 and 30 goals) and poor defensive records to make mutual scoring likely.
Pick: BTTS - Yes to 1.8 @ Casumo - Up to £30 Free Bet for New Players*
