No matter the result tonight, we will always qualify if we beat Nancy at home and Lech don't win at Feyenoord Rotterdam. That looks realistic. So, we might still survive if we lose tonight.
A draw would mean a huge step forward. If we draw, we don't be dependent on Lech anymore if we beat Nancy ourselves. We can even draw against Nancy, if Lech don't win at Feyenoord Rotterdam.
A win will qualify us immediately.
