Chelsea and Arsenal, teams with considerable experience in Europe, will kick-off their Europa League campaign this week. Both the London clubs are under the stewardship of new management this year.
Chelsea won the Europa league in 2013, the year after they had won the Champions League. Arsenal were knocked out of last year's competition after losing to Atlético Madrid 2-1 on aggregate.
There are a number of other clubs that could still challenge for the title.
