Manchester United striker Robin van Persie has been ruled out for a month with a thigh injury.

United boss David Moyes confirmed the Holland international had suffered the injury when he took the corner that led to Phil Jones' match-winner in the Champions League triumph over Shakhtar Donetsk on Tuesday.

"Robin van Persie is out for a month," said Moyes.

"He picked up a thigh strain in taking a corner kick which led to the goal."

Moyes added: "It is unfortunate because I think if you look at our record with Wayne Rooney and Robin in the team it is actually very good and we have not had them for quite a period recently.

"Marouane Fellaini has a bit of a back injury.

"Michael Carrick is missing and Robin is going to miss four weeks with a thigh strain. That is a big blow to us."
