Eight changes needed for career mode:
When playing a club only on career mode, have contract offers from international teams.
With the current players, have their player rating increase or decrease over the years depending on age.
When recruiting rookies, have their ratings increase over time not remaining at the same.
After a game has finished, give players who have played a score out of 10 based on statistics when played.
Give a man of the match to whatever player did the best performance.
