Although most (if not all) of these ideas have already been put forward, I just want to support them:
* Ability to complain about poor Refereing.
* Media events. Serious fouls (i.e. recent Thatcher event) - prep for a big game etc.
* Post-Match Interview (if you accept). Questions are asked about the game and about the future. These can have impacts such as improve or lower morale, create hype (and therefore expectation) etc. If you take part in enough, your reputation should recieve a small boost.
* Even more variety in the commentary.
* More indications of rivalry in matches between teams who are traditionally arch-enemies.
...and thats all for the moment.
