While managerial changes at United have done Rashford’s cause few favours, Rooney believes that a product of the Red Devils’ fabled academy systems needs to shoulder blame for failing to deliver often enough.
United’s all-time leading goalscorer told The Wayne Rooney Show podcast: "I think the environment hasn't been right but that is down to yourself. If you are not playing well or you get left out of the team then I think it is easier to blame the environment and whether that is right or wrong. I think that comes from how you apply yourself.
"In games we have seen with him where we know he can do more, we know he can run more - that is nothing to do with an environment. I might be wrong here, I really like Marcus as a lad and as a person but I think that is an easy one to throw at people."
