Real Betis leads Group F with eight points, one point ahead of second-placed AC Milan and third-placed Olympiacos, while Luxembourgish side Dudelange is at the bottom with no points and two remaining matches, reports Efe news.
The Spanish coach said at a press conference that he believes his Greek opponent "depends more on tomorrow's result to qualify," meaning it will likely be a tough match against a strong rival.
Setien explained that even if his side fails to earn a home win on Thursday, Real Betis would still have options to reach the Europa League knockout stage with a victory in the last match of the group.
The coach stressed that he is not concerned about Real Betis' recent La Liga defeat 2-1 to Villarreal on Sunday.
