United’s initial fixtures in the competition will now form part of a league phase, in which we’ll face eight different sides – four at home and four away.
Our continental campaign will begin on Wednesday 25 September, when we welcome FC Twente - Erik ten Hag's boyhood team - to Old Trafford, at 20:00 BST.
The second league phase fixture comes just a week later, with the Estadio do Dragao playing host to a reunion with FC Porto - who we famously played in Champions League knockout ties in 1997, 2004 and 2009 - on Thursday 3 October.
