If signing a new striker in the January transfer window was previously seen as a possibility for Manchester United, it now needs to be seen as a priority.
When they return to action next month, Anthony Martial will be the only recognised central attacking option, and they could be without the services of Marcus Rashford and Antony, depending on how far their respective nations get in the World Cup.
Even if they have their wingers back, the forward line looks thin. Martial has already suffered three separate injuries this season and can't be relied upon as a long-term option; Cristiano Ronaldo will never play for the club again; and youngster Charlie McNeill is still too raw a talent to be thrown in at this stage in his career.
