Maybe you're right... but, what if, there are no flaws, and we just underrate the meaning of age, height, weight and foot? I'm not sure, cause I'm at 4th Season, started to build up my squad with young players at the Beginning of 2nd Season. I bought three new 18 years old at the Beginning of 3rd Season, two 18 years old at the beginning of this season.
My best players this season are my "oldest" - 3x 22, 1x 21. If I check their rates, I see, the are way more to keep constant (ratings). But... on the other side... one of the new players (AMR), I bought, because my current AMR performed first three days extremly poor. Last season he was my best man: 61 goals, 35 assists.
My new AMR is also 18, but his performance is... worldclass: 21 games, 10 MoM, 27 goals, 17 assists. Worst rating was 8.
So I really don't know, what this was... I'll look on the upcoming three games before the cup-semi. It doesn't matter, if the squad perform well again, they can easily drop again - trust is gone, frustration is coming.
I always try to go for the triple, but if I'm beaten by a good team/good manager, it's okay - but if there's suddenly such a big drop... that's not normal...
I understand, if one single player has a bad day, but the whole defence and GK, while midfield and ST are doing their jobs?
