Sometimes you make your own luck in football.
Trailing 1-0 to Borussia Dortmund with five minutes to go in their UEFA Champions League match, Manchester City received a lifeline when referee Pavel Kralovec awarded the home side a penalty for a handball in the box on Neven Subotic.
Of course it wasn't a penalty. But again, most handballs leading to a penalty shots are like this one. And it seems to be really arbitrary and up to the referee to call it intentional or not.
Seriously, offensive players should stop trying to score a goal. Just get close enough and aim for the arm of a defender. That's easier.
