Football App Custom Icons

Hello fellas! This an Icon set I've been working on (and will have to keep on expanding and polishing).
This set is for a Football (Soccer for some) WebApp so players can organize games with their friends, go out and play for real.
The grid gave me quite a bit of work, but I'm pretty happy with the final result. I hope you like too!
Please, any feedback is greatly appreciated! And if you feel like it, press "L" and share some love! :D
