Great post, a really true statement, Faisal.
I once heard Andy Gray say, "After a game I had scored in I would try to replay the goals in my mind, to figure out how I'd score them, but I couldn't work it out. It was just instinct for me to get into those situations and score those goals."
I find dribbling the time you have to be most instinctive, especially with tricks. It's that extra work on the training ground, where you develop something you'll do in a certain situation, that would happen from nowhere in a game. I realised this at our ODP tryouts here, I do roulettes all of the time to try to beat defenders, but during a game we were playing I had a man on my back, and I controlled with my left, pushing it to my right and spun around the guy while dragging it with my right. Afterwards, by dad said the coaches said it was 'perfect' and that it was fantastic. Yet I couldn't hardly remember doing it, much less how I did it or why I did it.
I also really like your statement about finishing, mutu. I find I finish better in a game when pressured than given lots of time, and it's because of this, I assume. When you get the ball and loads of time, all of your different methods of shooting, of dribbling, etc. etc. go through your mind, and you get caught in two minds and mess it up. Should I chip? Should I bend it? Strike it firmly? Dribble around? Nutmeg him? So many options. However, when you get the ball with no time, then instinct comes in from hours on the training ground, and you pick the finish you found was best on the training ground. You alternate brain kicks in, if you will.
This is one of the reasons free kicks end up in the net a lot less than you'd imagine, too. For as much practice as can be done, when you're out there a million things go through your mind. Should I bend it with inside or outside? Far post or near? Driven? Pass? Haha, it really messes with your mind.
