Matthijs de Ligt scored an own goal on his first Juventus start but Gianluigi Buffon proved the hero for Maurizio Sarri's side as they beat Serie A rivals Inter 4-3 on penalties after a 1-1 draw in the International Champions Cup.
Having come on in Juve's defeat to Tottenham, big-money signing De Ligt was handed a full debut for the Derby d'Italia encounter in China, but the occasion was marred when he diverted Stefano Sensi's 10th-minute corner beyond Samir Handanovic.
