It's not yet known whether Rooney is just unfit to play two games so quickly or (more likely) injured, but heavy squad rotation was probably to be expected, and that's what we've got. Javier Hernandez comes in for Danny Welbeck, Michael Carrick comes in for Darren Fletcher, while Ryan Giggs and Shinji Kagawa make somewhat surprising starts. Chris Smalling is at right-back in place of the injured Rafael, with Nemanja Vidic coming in at centre-back.
The bench looks a bit tastier - Fabio gets a place once again, while Darren Fletcher is still in the squad, Wilfried Zaha is available, and Welbeck and Adnan Januzaj are there for a possible rescue act.
