Yes they are not strikers like Romario and Ronaldo that could run at defenses . But instinct is not their problem . Fred was a pretty prolific goal scorer his whole career . Jesus does have good instincts in the box. That’s not the problem IMO. Fred for example did find spaces in 2014 but often the ball never got to him. We shouldn't need a Romario or Ronaldo type of striker to win a WC. France just won a WC with Giroud not scoring a single goal. While that's extreme, neither Germany, nor Spain or Italy had those types of strikers when they won. Also, most of Ronaldo's goals were really well assisted. They were not a result of him running at defenders and creating opportunities for himself.
