Napoli goalkeeper Morgan De Sanctis has questioned Udinese midfielder Gokhan Inler's affinity for the club.
Inler scored a screamer against Napoli on Sunday in a 2-1 win for Udinese but refused to celebrate under the pretext that he has friends back in Switzerland who support the club.
At the time, speculation mounted that the real reason why Inler didn't celebrate was because he is joining Napoli this summer.
Interviewed by Il Corriere dello Sport, De Sanctis said: "I was angry with Inler for his powerful and precise shot.
"He didn't celebrate and justified it with the story of his Neapolitan friends, but I'd be careful about professing this Neapolitan-ness.
"I don't have much trust in Neapolitan players who play against us. It's easy to talk about Napoli when you're on the outside.
"I say 'Viva Napoli' and 'Viva' above all those who have chosen to be here."
