He said: "Last season was a bad experience for us in the group right from the start.
"It was important to get six points this time straight away with our first two games. That makes things easier to manage, certainly than last season.
He added: "The confidence is high and we aim to keep it that way. The wins over United and Everton have shown the team that they can beat anyone.
"Last season people were saying we could not beat the top three, but we deserved to beat United and it was the same against Everton. Those wins show how much we have improved.
"In such situations you do not need to say too much to the players, confidence is high and they know what they are capable of."
