may you have already recognized a new symbol next to your players (after they were promoted to senior squad). When you click on this little icon you get redirected to a page, where we show you how the player has developed over his career. We have collected information about the players in the last month, so that we are able to show a nice graphs for recent players.
Please keep in mind, that we can only see the player skills, when the player is still in your senior team or when he is on transfer market. If you have not run a sync in the right moment information could not be downloaded from HT. I hope that you can find some nice information about the skill development of your players throughout their career.
