Rumours began circulating that Pardew had handed in his resignation following Monday nights 3-2 defeat to Everton, and although those have proved to be false, the former West Ham manager is under severe pressure following back-to-back league defeats.
The Magpies made a decent start to the season, beating Fulham and Aston Villa.
But owner Mike Ashley has been particularly disappointed with the last two performances which saw a home defeat to Hull City, and a terrible first half performance at Goodison Park.
Pardew – who is in fact the league’s second longest serving manager after being appointed in December 2010 – said: “There is always scrutiny when you have lost two games and you’re at a big club.
“There is going to be pressure and social media has added to it. The bottom line is that this is a big club and you have to win games.
“Most of those rumours started on social media, probably by young fans, and it makes some sort of headway.
“The only way you can deal with it now that I’ve been a manager here for nearly three years is to cut yourself off and focus on the job. That’s all I’m doing.
“It’s the old saying that you can’t keep all the people happy all of the time. Well, I can’t keep any of the people happy any of the time!”
Pardew was rewarded with an eight year contract barely more than a year ago, after guiding Newcastle to a fifth placed finish.
But last season proved difficult, with the Magpies narrowly avoiding relegation.
