While I think things like vision, communication and teamwork, spatial awareness and improvisational ability are critically important and can't be taught (though they can be learned through lots of play), this article definitely shortchanges the amount of physical and technical skills required for soccer / football that can be taught and developed through practice

Good stamina is a prerequisite for being good at soccer / football. Players run 5-10 miles per game and a lot of that is intense bursts of speed with lots of changes of direction and agile footwork -- which is incredibly tiring. A team gets a limited number of substitutions and there are no timeouts / breaks other than halftime. So you have to be in good shape, and that's definitely a skill that comes with practice

Technique / "touch" is also critical and can be developed. The most immediately striking easily observable difference btw pros and less skilled players is that pros touch is just impeccable -- the ball just goes exactly where they want it. It's like a part of their body. That comes with drills and repetition.

If you are in good shape and have a good touch, you'll be better than most players up to probably a US division 3 college level (you can also be good at this level sacrificing touch for intelligence / game sense, speed, or another attribute). But beyond that you need to either have freakish skills / athleticism and good game sense or just really good game sense
