idk, but Maybe they create more than other clubs in the final third (Is a question.) They ain't paying the refs and shit that's for sure, and i also don't believe in bias. But if you play quick attacking football, you are more likely to get pens, simple as that.
That's what happens when you just see the score line and not the actual game.
Lazio got to 10 men in the first have just like Napoli. Lieva was sent off.
They were all over Napoli. Scored 3 goals all disallowed, Immobile missed a penalty and they hit the bar multiple times.
On the other night they would have crushed Napoli by at least 5 goals.
