Cooperation of clubs.
You definitely know what kind of co-operation these two teams have.
They have the same owner. "Red Bull" Company.
It should also be pointed out that Salzburg is practically one of the Leipzig brench office's
The situation on the table is such that Salzburg has already secured first place in the group, while the Leipzig team is necessary to win if they want to take the other stages of the competition.
I believe Redbull's goal is that both teams are in the 1/16 finals of LE and try to get as many rounds as possible because they bring money to teams and through prizes, through sponsorships, and through the sale of players from both teams.
