Napoli have signed Torino defender Nikola Maksimovic.

The Serb has joined for a reported €27m plus Mirko Valdifiori.

The negotiations have been dragging on since January and deteriorated three weeks ago when Maksimovic went AWOL from training in protest.

The Serbia international was held up in Frankfurt by a security alert, so Napoli sent a private jet.

He was whisked straight to Rome, but the delays meant he signed the contract in Frankfurt and faxed it over.
