Yes, Ten Hag needs a center forward; Marcus Rashford is a left inside forward; while Antony is a right winger; having to rely so much on Rashford goals is one reason why Manchester United fumbled couple of competitions in the previous season. If Ten Hag won;t get a center forward; then he needs to sign a Left winger; so that Marcus Rashford can be pushed up top in the no 9 position.
This kind of solution should have been thought of by Ten Hag at this point before it was too late, because Manchester United really need a center forward so they can score more goals and not just rely on one player like Marcus Rashford. Although it is not a problem if Ten Hag hopes that Marcus Rashford will score more goals, it will be more perfect and very helpful if there is one center forward at Manchester United next season.
