I do think there’s a tendency to ‘over coach’ young kids these days too. Academies are all the rage now where parents get sold a lie that their young Diego is going to get the best footballing education and the best chance to make it as pro footballer when the reality is the academies are made up of usually local people who have completed a two day football leaders award, this is all they need to be classed as a qualified coach at academy level. I’m not saying all the coaches are under qualified but coaching is only beneficial if it’s good coaching.
I coached my kids when young (I'm in the States), I had to take a 16 hour course and obtain a USSF E license (which I don't believe they have anymore).
If you wanted to coach above 14 yo, you needed a D license which was a one week course. This usually weeded out the parents (like me) and was made up mostly of college players 18-24 (the courses are hands on, I couldn't keep up with people that age). I believe you needed 6 months of experience as well.
There are three above that, but then you're getting into pro courses.
Our club had only volunteer coaches, so we were mostly parents who were just helping out.
The bigger clubs at premier level, which my kids played on as well, all had paid coaches and that was essentially their job.
Results were mixed, if a parent was motivated enough to do the course and help the club, they were generally successful people in their work and had a good attitude towards coaching (there were obviously exceptions).
With the paid coaches, mixed as well. Some were not very good and stayed on for a paycheck, or to never have a "real" job. Most of the good ones would only stick around for a year or two before they either got a better paying coaching gig, or had to get a "real" job to make ends meet.
The best coach my kids had was paid, he was there for 3 years. Was great with the kids, but didn't accept anything less than what he wanted out of them, and his teams always got better very quickly. At the same time, he was asking the parents if they had leads on a "real" job as he wanted to start a family and couldn't do it on that wage. Luckily he was hired by a local college to coach their men's team so he got to stay in coaching.
