Neville told reporters that a summer of relative calm in the transfer market has created a positive, relaxed atmosphere at Goodison Park.
He said: "We have looked into many things but I think it is the recruitment which has been most important. When it is done early there is not the uncertainty of who we are bringing in or who is leaving.
"Last season the panic and nervousness of the fans spread to the team and I have to admit the team were probably anxious as well.
"That calmness has gone into us all because we have recruited early and with eight days to go in the transfer window there is no panic if we don't bring anyone in."
Everton play their first away game of 2012-13 against Aston Villa on Saturday.
