Besiktas still have a good chance to qualify for the UEFA Europa League, but it will be easier for the team to do it through winning the cup, as in the championship the team is only in 5th place, and there chances to qualify for the European cups are only in the Conference League.
Ankaragucu in the championship is fighting more to stay in the Super League, so to reach the semi-finals of the cup is a great achievement for the team. Of course, Ankaragucu will resist, as they also want to get to the semi-finals, and there are no top opponents left in the tournament, but still I have little faith in the team's success on the road. You can also consider a bet on the final victory to insure yourself in case of a draw in regulation time.
Prediction: Besiktas to win. We recommend the “1 Win” bet, odds 1.72
