The Dutch defender proved decisive for his new side having struggled to adapt to life in Turin since his move from Ajax
Matthijs de Ligt said it was special to open his Juventus account with a Derby della Mole winner against Torino that sent the champions back to the top of the Serie A table.
De Ligt has been criticised for some erratic displays since joining from Ajax but the Netherlands centre-back came up with a crucial second-half goal in a 1-0 victory in Saturday's clash.
He turned home from close range after substitute Gonzalo Higuain knocked a corner into his path to help Juve reclaim top spot from Inter, who won 2-1 at Bologna earlier in the day.
