The big clubs join the Europa League on Friday, when the draw for the group stages will be conducted.
For others, the journey has already begun in the qualifying rounds that have been played throughout the summer.
With a place in next season’s Champions League, as part of the prize for the winner, there is added incentive for teams to clinch the trophy.

The Europa League Player of the Season award for 2016-17 will also be presented at the ceremony. Zlatan Ibrahimovic, Henrikh Mkhitaryan and Paul Pogba are the nominees.
