- The graphics could be a little better. I'm not talking about 3D (for now!), but you could use some better sprites. It wouldnt be expensive to hire a 2D artist to create a couple of better sprites than the ones presented in the game.
- The player could actually WALK when moving sideways before the service, not sliding the way it does.
- You could add a new dimension to the game: managing the player's personal life - which would have effects in the players skills. You gotta know a game called New Star Soccer 3, they do it in a simple but very enriching and entertaining way.
- Media and relationships with other players would be a good add too.
- The music and sound suck hard - pardon me, but i just had to say it

- More statistics.
- Aging, retirement and arrival of new players.
The rest is great.
