"We are doing the same things in training and we are trying to play the same way as we did at the start of the season," said the defender.
"But confidence is a big thing and if you are high on confidence then you can play better because everyone wants the ball more and I think that showed against Newcastle.
"We had a good result and a good performance against Bolton two days earlier and we took our form from that into the Newcastle game.
"Overall it was a very good performance except for conceding a goal right before half-time, which we shouldn't have done.
"But that's football and it was probably a bit unjustified that they got a goal back when they did, because we could have been six or seven up.
"The important thing was we didn't let it affect us and we responded in the right way by getting another goal at the start of the second half.
"We are top of the league, so confidence is high and hopefully that will continue."
