Arturo Vidal netted in the opening minute of the Derby d’Italia, though Kwadwo Asamoah was clearly offside in the build-up.
The Nerazzurri went on to win 3-1 at the Juventus Stadium, ending a 49-match unbeaten run for the Bianconeri.
“After 17 seconds I was worried that we were off to a bad start,” revealed Moratti on Premium Calcio.
“When I saw the replays and that it was offside, I thought we were back to the usual story. The players did well and reacted to the injustice.”
