Ok. I've just been rereading the thread by the God that was Al Svanberg, and it seems that I'm wrong in thinking that there is a decrease in training ability before 22 years of age.
I stand corrected.
However, if a few thousand Top Eleven players would like to contribute, say, 5 euros a month into my personal bank account I'll spend some of it to work full time to find out exactly how training and player development works!!! Honest. I would. I'd post my findings in the forum and the holiday photos in Facebook.
Ha. Ha.
