The problem with applying analytics to Martial is the limited dataset - he only made about 50 appearances in his career before joining United. It's looking a good bet so far, but it's definitely a punt.

With young players, you take quantitative factors more into account than an older player. Staff and players at Manchester United have mentioned in interviews how Martial is extremely mature for a 19 year old, he is married with a child and obviously wants to provide for his family. The fact that he is French with limited English, means the tabloid horseshit rolls off his back and doesn't detract from his game.
