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.
Of course, Rashford cannot carry the whole load alone. The team needs a very good striker. I liked Nkunku, but Chelsea acted before them and made a serious transfer. If Manchester United want the championship, a striker is a must, they must find it. If there is a striker of this quality in their infrastructure, I think they can make it to the A team as a backup.
The summer transfer window is half gone already and Manchester United is yet to find a world class striker than can perfectly fill in the boots of Cristiano Ronaldo that left the club last December.
Marcus Rashford who in many occasions was used as a top 9 striker last season isn't known to bring our his best in that position. Rashford is better used in as a left wing attacker. So for Manchester United to do better than they did last season, they need to sign a known striker this summer
