Kwadwo Asamoah scored a goal to help Juventus clinch the Italian Super Cup with a 4-2 extra-time victory against Napoli on Saturday. The Ghana international equalised with fine volley for the champions 10 minutes after Napoli took the lead through Edinson Cavani in the game played in China. Goran Pandev restored Napoli's advantage before the interval. Back from the break, Arturo Vidal leveled from the penalty spot before Napoli lost Pandev, Juan Zuniga and coach Walter Mazzarri to red cards towards the end of the 90 minutes in the emotionally-charged contest. An own goal from Christian Maggio and a further strike from Mirko Vucinic then clinched victory for the Serie A champions in extra time. Asamoah's goal was his first for the club as victory earns him his maiden trophy with Juventus.
