Players position

[Maestro_itai_NL]

So I used to play OSM back in the day where you would be able to play strikers as LF, RF and ST. This wouldn't effect the game result... Is it nowadays the same thing?
So for example.. I am using the tactic to attack through the wings... Would it benefit me to put my Haaland upthere instead of using him as a ST?

Thanks in advance.
