from previous experience it might go like this for Maribor :
anyone with Spartak (26.09.17)
then anyone with 7, then 6 then 5
Villarreal (28.04.16)
Borussia Dortmund (07.04.16)
Manchester United (17.03.16)
FC Augsburg (18.02.16)
FC Sion (10.12.15)
Rubin Kazan (05.11.15)
Bordeaux (17.09.15)
dont think they need to go back any further !
this could be an alternative :
anyone with 8, then 7, then 6 then 5
Spartak (26.09.17)
Villarreal (28.04.16)
Borussia Dortmund (07.04.16)
Manchester United (17.03.16)
