Basically the scope is because our coefficient is 29.054 (or something similar), we're gonna be one of the top 5 teams in regards to coefficient in the 3rd Qualifying round.
Which if you're basing benchmarks from prior seasons. Grasshopper Zurich (9.855) in 2016 was the "best" side we could have faced. But what will happen is we'll know of the 5-6 teams we could face before hand as they allocate teams into groups (I'm not sure what the procedure for that is mind, i believe it could be absolutely random), then they just draw balls from each pot usually numbers 1-5, 6-10 and whichever is out first is at home first and so on. So e.g. they draw our teams "3" vs. "8", we'd see all those drawn.
From this years draw, there are very few unseeded teams I wouldn't fancy our chances against, some iffy ties like Osmanlispor, Basaksehir really.
Gets tricky in 4th Qualifier.
