I generally agree with what rubikks said, but...

The tune could stay if it was some atmospheric game set in for example 1920s. I LOVE the idea of playing as a referee. I haven't seen it ever before. Keep working on it. Graphics don't have to be exceptional, you can even keep everything minimalistic, like a bunch of black-and-white dots (representing players) moving round a grey rectangle (representing a football pitch).

Maybe keeping graphics very simple would help. I see you're not an artist :P so, if you want the game to look serious, try doing that. If you take it as a long-term project, then you can use its potential and create something big.

huh??

didn't have a clue what was going on

long review ahead

This game has some potential, but it's chock full of issues and flaws. Firstly, the music is hardly fitting to the game. Try going with a bit more of an international tune, something more foreign than classical.
Nextly, there's no penalty for random clicking. The player should lose 10 points or something like that if they click on a non - angry player. Otherwise, I could just spam mouseclicking all over the place and still get a high score.
It didn't really seem like they were playing an actual game of soccer - it was just a bunch of guys sporadically darting around a field and randomly getting mad.
Finally, the game itsself just feels a bit rough and unpolished - better graphics and some flashy effects would be a welcome addition.
I'd also like to say that the player should have to settle a wider variety of issues, such as fan interference, unsportsmanlike conduct, etc.
Beyond that, this game has a lot of potential and I'd love to see it go somewhere.
