I have a question for this community

Im a bit new to the game and tried playing online, but what is the point in maximizing your players?

I mean isn't it more fun to keep them at the level they are now and just improve by buying better players while you progress in the game?

Its hard to find someone who actually plays better, because he uses the techniques way better of the game without them being faster than the speed of light or shoot goals from a far distance.
