When a player starts to seem concerned about he should be play more games, player talk options are not satisfactory.
Example :
I have played 15 games at leage and 6 games at Champions League. Player started all CL games in the first 11 and 10 league games, but he looked unhappy.I can say "You are a valuable member, i will fix this", or "I will put you in Cup Games", or "I think your a backup player now, you have to get used to it" etc. But I want say him, "Hey, You are playing enough, no need to worry about your first team place".
