Gokhan Inler joined Napoli from Udinese on Monday and was unveiled at his new club dressed as a lion.
Napoli president Aurelio De Laurentiis invited a man wearing a lion's mask and asked him to remove it, and to the amazement of all, it was the Switzerland midfielder wearing the Napoli shirt.
Speaking to the media, Inler said: "All that matters is Napoli and every game will be important as we are in three competitions [Serie A, Champions League, and Coppa Italia].
"I decided to come to Napoli a long time ago and now this is a new chapter in my career and I want to give my best.
"I want to win here for the fans."

The 27-year-old was presented by the Italians on board a cruise ship as the club showed off their new kits for the upcoming season and Inler was given the No.88 shirt.
Napoli did not disclose any financial details, but previous reports suggested a €12 million agreement was reached with Udinese for the transfer.
On Sunday, Udinese coach Francesco Guidolin said his club would replace Inler once the midfielder completed his move south.
