Sometimes, fights are pretty straightforward. Sometimes, fights include two entire teams and flying kicks.
This is the latter.
Fights are like onions. You have to peel back the layers.
Layer 1: They're mad at each other.
Layer 2: No hands.
Layer 3: Flying feet with studs on them.
Layer 4. More flying feet with studs on them.
Layer 5. Repeat layers 3 and 4.
And that is how a match winds up with eight red cards. Who said local Brazilian leagues lack depth and sophistication?
