Salary cap
The fact that you can choose a salary cap in the start of the season is great for balance, except for the fact that it is almost impossible to win the PL with the salary cap of the PL champion and it is just not fun having to tank during 10 seasons on top 4 to have the funds just to get beaten by a random PL team that just don’t give a damn about the cap, besides that, the problem is that the computer has a lot of players they don’t even use (and their salaries are ridiculous) impeding the player from recruiting any great players. A very nice thing to do was improve the odds of winning a game based on the chemistry cause I think it is a bit of a bummer having all the effort of hiring the right personnel, change the players style of play and everything just to get beaten by a team with lower overall and lower chem (on a regular basis).
