I understand that for people here some S&C in soccer (at the highest level) might be crap.
But hold on one second.
Let’s say C. Ronaldo or Drogba or Rooney etc. are not properly implementing a periodization scheme/strength training etc., BUT, despite the allegedly awful S&C they are somehow able to score, let’s say, 30-40 goals each season.
Now, if I were their S&C coach, I would say something along the line of “do exactly what you did last year”, because I’ve got the impression it’s working.
As for soccer players being not physically/athletically developed, I think it’s a thing of the past. Mow matches are very fast and physical and the greatest difference between lower and higher level players is the physical component.
