This is probably way too late.. but.
I find that the training system is lacking. The sliders in the game give you no real indication on training at all, also you never really know how the training sessions went, if a youngster is training well, looking awkwardly for his "position". There are plenty of players out there who play in the wrong position as youths. I'd like some kind of indication from the assistant manager exactly how each and every one trained. Especially youths. "Guiseppe Rossi trained exceptionaly well and is showing great promise in the forward position, He's developed his shooting quite well and could possibly focus more on pace, as this is a lacking attribute." Of course the better the assitant Manager the better reports you get. But I would really like more information on how my players perform in training. The current Did well did poor is not enough in my opinion. Especially not for youngsters.
I would also like to point out that even though most clubs train together and in specific groups. Each player has his own "scheduel" and specific areas he should improve. In the current game you can't have training groups AND individual training, you can only have one. Which is slightly frustrating. As a rooney would not need the same kind of training as Huntelaar and Saha, I believe it should be possible to assign indivudal training in addition to the group training.
Player Problems and Team Chemistry
Also in real life managers have to deal with a players problems. Some manager tell their players to get over it, and practice a disiplinary line, but some managers tend to "help" their players. I'm not sure how it would be included, nor if it should. But I just think that player involvement is lacking. A manager is responsible for his players, and needs to help them through the rough patches, be it personal problems or problems on the pitch. "It seems Rooney and your new siging Nani isn't getting along too well. It could be smart to find out what is bothering them" basicaly with problems within the squad, a squad can't function. Team Chemistry is very important and could make the difference from fourth place to champions. Who you choose to talk to will eventually lead to more problems or a resolve, based on the proffesionality of the player and his influence in the squad. Chosing to take the less influental players side might cause the other team members to respect him more.
Youth Team development, it is one of the most important aspects of football today. Even though forgotten by the media and ignored by many, this is where the talents come through. The possibility to have a proper youth academy, with reports, match results, training reports, development stats (monthly, "this player had developed well in this and this area but are struggeling to keep up with this and this") and "talent scouting", scouts who are specificaly used hired to find young talent in youth devisions and such, would be great. Possibility to see the youth matches without managing them. This could help you determine what kind of youngsters you should be looking for and if you should go ahead and buy a new player or wait for the young one to prove first team worthy. The same "individual" training with youths, but with even more detailed reports on their progress, current ability, current proffesionality ("We consider Tommy Hinchly to be a model proffesional") expected growth curve, positional ability and relationship with different coaches. A youth player needs a "main coach" who can help him with personal problems and encouragement, someone who's "responsible" for his growth as a player. If the youth dislikes this person, he will most likely never give it his all and never develop into a star player. Of course the manager does not need to know about these problems, so theres no reason to code that into it, and the relationship could be random. However I do believe nationality, personality and area of expertise should come to play into this. A player with roughly the same personality as another player is more likely to get along than someone with complete different personalities. Also, when it comes to the whole learn from player part, I believe you should have some sort of indication of who on your squad the youth is similar to, it would help a great deal in making good matches and I would also think that not only the young player learns from this experience, but also the older player. May it be sportsmanship, technique or flair. A young talented player who train with you often will always cause the older player to feel a sense of responsibility and often sparks life back to his passion. If not technically, a young player would help the older player mentally and personality.
When it comes to penalty situations. There is no way we can see if the player dived or not. Of course as a manager you're supposed to see this. But since we only see Dots, I really can't figure out how we'd see if a player dived or was tackled. Is there anyway you could have someone or something tell you if it really was a penalty or not. And if you do say you believe the player dived, the player will lose some faith in you if unproffesional, or get his act together if he is proffesional. Instead of the FA becoming angry with your answers regarding penalties you should make it affect the player. And make it so that we know with 70-99% certainty if it was a penalty or not.
The Thing That Annoys me 90% of the time
One last comment about one of the match comments
"The Team couldn't have dreamt of a worse start" You don't dream of bad starts you dread them. It doesn't make sense to dream about horrible starts of a match and frustrates me.. I might be the only one annoyed by this, but yeah... seriously annoys me. Don't know why..
