Where do you shine on the pitch?
Much of what I talk about here is on self awareness and knowing what you're good at and where you need work. It's important because if you spend you're entire time trying to improve at a position that doesn't come naturally to you, it's going to be much harder for you to make it to the top level. Becoming a professional footballer is an incredibly tough task and I believe you should give yourself every chance to do so.
So how do you do this? I think you give yourself your best chance by focusing on what you're good at and becoming tunnel vision on this. This takes self awareness to know in what areas you excel in and what areas you struggle. For example, a player like Mohammed Salah hasn't seemingly spent much time working on his 1v1 defending. He's developed his dribbling, speed and finishing ability. He has worked on his strengths so he could excel in this particular area.
The point here is that you don't have to possess every single attribute of a professional footballer and overcomplicate your game. If you know that you're a strong attacking player then focus on training the attributes required of a top attacking player. Don't spend time on your defending, your coach will help educate you here.
Now, I'm not saying in this article that you should never practice or train your weaknesses. If you're a poor dribbler and play as a centre back, then practicing your dribbling is still important because it's one of the fundamentals of the game. However, in most cases you are going to be limited to the position you normally play on the pitch so you need to make sure that you are far better than everyone else in this position.
Making it to the top level is incredibly difficult and will require hours and hours of training by yourself. Your best chance of making it is to perfect the parts of your game that you're naturally good at and stand out in these areas far more than anyone else.
