The button to stop or resume skills would be good if in case of training you want to upload other characteristics to your players in general and they all have skills or role in training as well so the player can upload those other characteristics and then in game resume those skills. So in a way you do not have to go from player to player to resume or pause the skill or role.

Many times it happens that we are in champions or cup and we see some very good team in another line with respect to ours and we look to see their template and we are attracted to a player, it would be nice if we could have the assistant following that player, who would inform us In a regular way each player that we select and then in the transfer market we could give some offer or something
