I think qualification round 2 is the last one and whoever wins this, is qualified for the Europa League?
No, it doesn't. We have one more round (the third qualifying round) starting with the first leg on 7th of August, and then we have the Play-off round. The teams that will win those ties, advance to the league phase of the Europa League. The defeated teams will switch to the league phase of the UEFA Conference League. The road is long from the start...
