Robin van Persie is set to miss eight games

Robin van PersieManchester United striker Robin van Persie has been ruled out for a month with a thigh strain.

The Dutchman, 30, was injured while taking the corner that led to Phil Jones’ winner against Champions League opponents Shakhtar Donetsk on Tuesday.

Van Persie has endured a campaign disrupted by injury so far after suffering toe and groin problems. Last weekend, he had returned from a month-long absence in the 1-0 defeat to Newcastle.

He arrived at Old Trafford for £24m from Arsenal in August 2012 and scored 26 goals last season as United claimed the Premier League title.
