Premier League heavyweights Chelsea and Arsenal will get their UEFA Europa League campaigns on Thursday as the group stage begins with respective fixtures against PAOK and FC Vorskla Poltava.
Chelsea are yet to drop a point in the league this season and will hope new manager Maurizio Sarri has the keys to unlock Europe's secondary competition, having last lifted this trophy in 2013 when Rafa Benitez was in charge.
Arsenal have a new chief of their own, and Unai Emery certainly has Europa League nous to share after he won this tournament three seasons in succession with Villarreal between 2014 and 2016.
