The England striker is suspended for Newcastle's visit to Old Trafford this weekend, when Newcastle are looking to end a 41-year run without a win.
Pardew admitted: "Swansea didn't have their two main strikers last night and I don't think they could have played any better.
"But he is in terrific form which is great news for England and Manchester United and for us, it slightly helps us that he won't play. But I don't think they will play any differently.
"I think there will be a reaction from Manchester United from their defeat as there will be from us, it will be a pressurised game so it will be a time for calm heads. They had been on a run of 12 games unbeaten so it is not like there is a crisis there.
"There will be pressure but we have to capitalise on that and make it difficult for them and try reverse Newcastle stat of not winning at Manchester United which is not very good."
