How often are the reports wrong?
I have a player who I was told,
"He seems to have a lot of potential of becoming a fantastic player."
I've seen his primary ratings as high as 84 but usually when logging in his value are in the red and have dipped as low as 72. I realise about the player profiles being different and they make take up to the age of 24, I think, but it seems a bit odd that this one player can't get it together, or is the coach just a wind up merchant?
Never trusted coach reports, but I guess they can be source of hidden information. Have you tried asking for a report on your own?
