United were beaten by his former club Everton on Wednesday night as United have collected just two points from their last four Premier League games.
The United boss admitted his side did not take their chances at Old Trafford on Saturday but he believes, with some hard work, the results will come.
Moyes said: "I'm disappointed with the result. I think we needed a bit of luck to go for us and opportunities to take them a bit better for us and that didn't happen.
"We've lacked a little bit of creativity at the right times and when we've a chance to win some passes but not quite made them.
"We've lost the two games 1-0 and both have probably been slightly against the run of play we've lost them and that happens, we have to expect that here.
"So we have to create more chances and more opportunities and play better. That's the way to do it.
"There will be (light at the end of the tunnel) because it is that transitional period which was always going to be the case.
"We hoped that it wouldn't be quite as poor as it has been in the last few games but hopefully we'll get that right."
Yohan Cabaye fired home his third goal of the season to condemn the Red Devils to their second successive home defeat for the first time since 2002.
And Pardew was morethan satisfied with his side's performance as they moved up to sixth in the Barclays Premier League, admitting the win was among the best things he has experienced during his tenure.
He told UK press: "One of the top (moments in charge) obviously, 41 years we've been waiting to win here as a club.
"It was a magnificent performance but I know we probably won't get the headlines because poor old United and David (Moyes)....difficult result for them.
"I asked them to play very differently today to the way we've been playing. To keep the ball and control the game and we did that. We kept the ball well.
"A great day for Newcastle United and our fans, it really is."
Pardew was quick to praise Hatem Ben Arfa, who came on as a second-half substitute.
He added: "I though Hatem changed the game a little bit when they were coming on to us because he just changed the emphasis, which he can do and he now knows what he needs, the work rate you need in this team.
"If I can get him in the team and playing like that every week we'll have a great side."
