Oestersunds FK have played a different formation in all five group matches thus far, so it remains to be seen how they will line up on Thursday.
Still needing points to secure top spot, the Swedish outfit should play their best XI against Hertha Berlin.
Hertha Berlin can only finish as high as third in Group J and that would require Athletic Club beating Zorya in the group's other game.
Oestersunds FK are currently two spots clear at the top of the group and have been the surprise package of the Europa League this season.
The Swedish outfit have won five of their last eight matches and will fancy their chances of getting a result in Germany, particularly as Hertha have nothing to play for.
Hertha Berlin have only won four of their last 17 matches in all competitions but are unbeaten at home in the Europa League this season and are yet to concede. It's a difficult match to call and could depend on what sort of team the home side field.
