Rooney specifically identified Shaw and Santos as the players who need to be sacrificed when Manchester United host Ipswich on Sunday.
Suggesting Patrick Dorgu should move to the defence, Rooney explained: "I’d change Luke Shaw and I’d play Dorgu at left-back, be a bit more aggressive. I don’t think we can rely on him [Shaw] to play all the games so when you’re playing against a newly promoted team at home, I’d play Dorgu at left-back." When asked about adjusting the midfield pairing, Rooney added: "Mainoo probably, yeah. I’d bring Mainoo in for Santos."
