It's been a very long time since Sturm have made it to the group stages of European cups, as the competitiveness of the Austrian Bundesliga has changed in recent years, with first place always now occupied by Salzburg, with other teams from the championship struggling to get through qualification.
Sporting regularly play in European cups, with the club most often playing in the UEFA Champions League, where they also struggle to get out of the group. Last season the team even reached the 1/4 play-offs of the UEFA Europa League, beating Arsenal.
The group Sporting got quite dangerous, it is unlikely that the Portuguese team will play with the second team in the first matches.
Prediction: Sporting to win. We recommend the “2 Win” bet, odds 2
