If Vincent Kompany wants to lead Manchester City to Champions League glory this season, he might want to steer clear of giving Sergio Aguero mild concussion.
City's captain inadvertently belted a ball in the direction of Aguero as he intercepted a loose pass in a training session. Unfortunately for the Argentine, his face was on the wrong end of it.

Thankfully for City supporters, Aguero didn't appear to be too rattled after it.
God only knows what would've become of Rivaldo if this had happened to him.
