Newcastle's topsy-turvy season took another twist with a surprise 2-0 win over the Premier League title contenders at St James' Park, which lifted them to ninth place in the table.
Pardew's side visit Tottenham on Sunday and he is convinced there is more to come from his side.
He said: "There are a lot of clubs who would envy our position as we sit here today and we have to always think that our glass is half-full rather than half-empty, which I think sometimes we do up here.
"I think we are in better shape than we have been given credit for. But this week, I have seen a lot more positive press about our players, who have been terrific. We have had some great performances.
"This is the end of a difficult period, in my view, of games for us because then we have got two home games (against Norwich and West Brom) and it could put us in a great position if we get a win against Spurs, or a draw even, so it's an important game for our league position."
Newcastle have lost on their last four league visits to White Hart Lane and Pardew knows the win over Chelsea will count for nothing on Sunday.
"Again, we are going up against a very accomplished manager and a very, very strong team at a venue where we haven't had good results, so therefore it's something we want to put right," he said.
