The Europa League group-stage draw is done, but what are the main storylines? See the full draw here.
What are Man United's prospects in Group L?
It will be a trip into the unknown for United, who will become the first English side to face Kazakh champions FC Astana. As well as a nine-hour combination of flights for fans, the trip will require mastery of an artificial pitch and an opponent that, while they should be beaten comfortably at Old Trafford, have a formidable European record at home. Astana have won nine of their last 11 Europa League games at Astana Arena and disposed easily of Rennes, who ran Arsenal close in the knockout stages, last season.
