What hee meant is that if you are consistent with your practice. If you keep practicing your skills and training to improve them, you will see benefits along the way. But yeah, there is a certain time, after a series of continuos practices, after a good time of training hard, when you reach a form, that you really increase your levell big time. For proffesional's imo, they reach this peak, after continuous training around january/february of each season. Thats when you see Messi starts scoring hattricks, and players reachh a level that's way beyond what they where in the beggining of the season. After training 2-3 hours per day, for 6 month, your body finally adapts, and you blast past your previous level... Its an interesting phenomenom.--
David meant you should keep training, and you'll improve everyday, somewhere along 5-6 months, you'll start playing one day, and then notice that you aree doing things with total ease. That your crosses are grat, your shots are exellent, your foot coordination is spectacualr. It makes sense too, if you do a series of cone drills today, tomorrow you'll see small results and benefits... If you train your dribbling and all your skills for a longer period like david said, you'll see biggerr imprvements with time. The key is continuity, and to understand that you're as good as you train to be.
Not only does this happen to players, it happens to team's. If you are on a team with players for 1 month, you'll play better than if your in a team with players for a week, but not as good as if your in a team with them for 6 month. Look at Spain
.... On the other hand, look at Argentina.
