Juve shook off their poor season start to thump cellar dwellers Udinese.
"I liked the attitude and the dedication of the team. We were precise today and it's a great morale-booster, but must not rest on our laurels," said the Coach.
"I was particularly glad to see we remained concentrated right to the final minute, despite the fact we were leading by a healthy margin."
Del Neri caused controversy among the fans last week when he suggested Juve were not Scudetto material.
"I said we will not set limits for ourselves and we have what it takes to not set any limitations on our ambition. We know there will be difficulties, as this team has only just been born and Juve don't have much patience to wait.
"If we play like this, then naturally the results will come. If we play the way we did in Bari, then it becomes difficult.
"I think my players are the best in Italy. We have midfielders who can adapt very well and in defence Zdenek Grygera impressed on the left."
