It's a common misconception that shoulder or elbow contact is relevant under the rules any more.
Using elbows for contact is not illegal, nor do you have to make contact only shoulder-to-shoulder.

What you aren't allowed to do is make contact with another player below on the elbow on their steering arm. And that's the only thing you might be able to call Luca on.
