"I was curious to see our reaction," said Ranieri. "The lads got off to a strong start, the approach of a team that wants to win. We worked all week on the movement of the full-backs, Zdenek Grygera and Hasan Salihamidzic.
"Genoa play good football and if you leave them space they will cause problems. We kept the pressure on to force errors and remained compact in a 4-4-2, helping each other."
Ranieri added: "A bad day at the office can happen, but we are Juventus and must therefore always give 100 per cent. I accept criticism when it is constructive. I have been in football for 40 years and just ignore the other talk."
Genoa boss Gasperini looked back at the opening stages, when his team had the upper hand ahead of Grygera's opener.
"I have to say we had a good start, but made some mistakes in serving the strikers. Juve scored and from then on it was all more difficult.
"We were penalised by those two incidents that made a big difference in a match where we played pretty well. If we had scored in the first 10 minutes, then the game probably would've taken a different path."
