From the UEFA Europa League app:
So what’s different in the UEFA Europa League and UEFA Conference League draws?
Not the software: it is the same already in use. Thanks to its flexibility, the system can either draw opponents to all teams one after the other – as in the UEFA Champions League – or draw all pairings instantly with a single press of the button. The latter will be the case for UEFA Europa League and UEFA Conference League.
What will happen then?
One event, two draws: The UEFA Europa League draw will be followed by the UEFA Conference League draw, both taking place within the same ceremony.
Digital draw system: No physical balls are used on stage. The draw button is pressed once at the beginning of both draws, thus activating the random selection of opponents, including who plays at home and who plays away.
Reveal: After the software has conducted the full draw, the pairings and who plays each fixture home or away will be released progressively, pot after pot, starting with Pot 1, thus maintaining suspense and clarity for viewers.
When will the match calendar be known?
The teams will know all their opponents by the end of the draws, however the fixture lists with match dates and kick-off times will be elaborated afterwards and communicated by Sunday 31 August at the latest.
Hope that clarifies.
