He's not exclusive to this, look at what has happened to Dele Alli this season. English media built him as an all action dominating midfielder who can play box to box for likes of Barca and Madrid, it's gotten to his head hence the constant flicks and ambitious passes he keeps trying this season.
Same has happened with Rashford, he always had this confidence about him which is good to see in a young player but it's gotten to the point where it's detrimental to the team. Going for top bin from 30 yard makes sense when your team is comfortable and cruising but not in situation like today. I can't recall many instances where one of those shots for him have gone in, maybe in League Cup earlier this year. Also, ever since Martial has gotten a run in he's even more hell bent on going for glory.
