Napoli midfielder Andre Frank Zambo Anguissa has told fans not to doubt his commitment.
Anguissa took to social media after defeat to Spezia.
"At times football is cruel and we saw that this evening. We must fight to the end, so let's stay united because we win together and lose together.
“I wish a happy Christmas to all of you and your families."
One Napoli fan wrote back, claiming: “Your mind is already on the Africa Cup of Nations, unfortunately for us."
However, Anguissa would not stand for that and replied in Italian: “I am not like that, brother."
