Javier Hernandez makes a start for Manchester United as David Moyes attempts to continue his progress through the group stages.
Wayne Rooney is the partner for Hernandez, although worryingly, amid rumours of a fallout, Robin van Persie is not on the bench. Oddly neither is Danny Welbeck, but Adnan Januzaj is, Shinji Kagawa taking his place in the first team.
Fellaini also returns to the subs, so Michael Carrick and Ryan Giggs comprise the midfield - also worrying. Phil Jones continues with Jonny Evans at centre-back.
Manchester United lineup (4-4-2): David de Gea; Rafael, Jonny Evans, Phil Jones, Patrice Evra; Antonio Valencia, Michael Carrick, Ryan Giggs, Shinji Kagawa; Wayne Rooney, Javier Hernandez. Subs: Anders Lindegaard, Ashley Young, Adnan Januzaj, Marouane Fellaini, Nani, Smalling, Alexander Buttner.
Real Sociedad lineup: Claudio Bravo, Carlos Martínez, Mikel Gonzalez, Iñigo Martinez, Alberto De la Bella; Markel Bergara, Zurutuza, Xabi Prieto (c); Carlos Vela, Haris Seferovic, Antoine Griezmann.
