he also lost a header with Anguissa in the first half, where he almost scored from corner - free header for Naples (around 40th minute - ).
Im not 100 % sure that first goal is totally on him, but who is he marking there if not Anguissa? when u look closely at him during this first goal action, he looks completely out of place there, not even knowing what is happening.
Then there is Lukaku chance that Di Gregorio somehow saved - there he completely looses Lukaku and leaves him with a free header - totally on him (around 49th minute).
Around 61th minute he is once again completely loosing marking in the penalty area, Lukaku is like 2m meters off him completely free - he is lucky that the cross was actually not directed to Lukaku - if it was, he would have easily scored. This led to a chance for Politano that Cambiaso blocked.
So i just looked at the extended highlights and u can see 3 amateurish errors made by him in his positioning.
For me, for the goal, its also on him, but McKennie could do better there too.
