I can see Welbeck becoming United's Aaron Ramsey once we get a managers that can have faith in him and plays him consistently in a false left wide role of a 4-3-3 system(I can not see him getting a run as a striker due to the competition). Like Ramsey, Welbeck has his critics that taught he is not good enough for their respective club. Moreover, their talent are/were both deceptive, with the factor of being indecisive in the final third, holding Welbeck potential back.
Welbeck is world class in almost every facete in his game beside what it is most important as a forward; being decisive in the final third. Looking at some of his highlights this season, I will be interested towards how Louis Van Gaal would sculpt Welbeck into a better player. He is perfect for his total footballing philosophy, so it would not surprise me if he becomes a favorite of his. The only problem is whether Van Gaal will implement a static left midfield role that would restrict Welbeck freedom, or adhere to his total football philosophy and implement a dynamic false left wing role, which Welbeck is more proficient in. If, it is the former, it will be a continuation of the debate that Welbeck is incapable of playing as a wide forward.
