Immobile's shameless acting, and Sterling's very weak penalty, as bad as they were on their own, will help to have better refereeing in the final, imo.
I think the ref in the final will be extra careful not to whistle whenever Sterling, Kane, Immobile, or anyone else falls in the penalty box and if someone dives or falls after the slightest of contact, he'll be immediately punished with a yellow card.
Mostly this will be bad news for Sterling and good news for Italy.
