The highly-rated Dutch defender put through his own net on his full debut, but the Bianconeri boss is not concerned about the former Ajax captain
Maurizio Sarri hailed Gianluigi Buffon's performance in Juventus' penalty shoot-out win over Inter, while insisting Matthijs de Ligt has no responsibility for their poor first-half display.
Buffon made three saves in a shoot-out to earn Juve a 4-3 victory on penalties following a 1-1 draw in Wednesday's International Champions Cup clash in China.
De Ligt's own goal 10 minutes into his first Bianconeri start handed Inter the lead, with the new signing turning into Juve's net from Stefano Sensi's corner.
