I wrote about one football game before. It is called Nation Soccer and its source code is available as well. One of the submitted games is basically a highly polished variant of this game. It might be worth checking the source code out!
Anyway, here are the games submitted before the event starts in Brazil.
Miniball Tap Football by Naked Penguin Boy UK
A simple reaction/puzzle game that I have seen before, but the football theme suits it quite well. A good timewaster, but it got low ratings. Probably the levels get too repetitive after a while.Google Play Store
Puppet Soccer 2014 - Football by NOXGAMES
This game is the one similar to Nation Soccer. The original game was fun and this one brings a lot of new elements. The game even has real footballers drawn as caricatures, really cute. The only thing missing is Brazuca! Well played with the keywords in the title.Google Play store
Super pocket football by Inlogic Games
Finally a football game, when you actually play football :) It is 2.5D and it reminds me of games I used to play when I was little. The game play can't match games like FIFA 14, but not bad for a change.Google Play store
