I grew up in Germany and played there since I was three years old. Currently I play indoor soccer in Australia and coach junior teams at the local club.
Overall I 40 years of experience, including playing, watching, coaching and analysing the game.
There is a lot out there in the market so I am interested about your approach and how you want to present it. I can definitely share drills with you but would need the age group you're interested in.
In regards to the drills, it would be good if you could specify the format you need the info and what info.
My suggestion would be:
Topic of drill; goal of drill; age group; organisational details: balls, bibs, markers, players.
I am looking forward to hearing from you.
