Wayne Hennessey has made two high profile errors for Crystal Palace in their recent matches.
The Welsh international had been in fine form, but he has made high-profile errors in both of Palace’s most recent matches against Aston Villa and Manchester City.
And Pardew claims that Hennessey has been told in no uncertain terms that he needs to improve.
"Wayne will play Saturday. He's battered and bruised, though. We've not let him hide from those mistakes,” Pardew said in the Daily Star.
"He's a laid-back character, not one to lay in bed and worry at night too much, but I've made him worry.
"My process has been to get him out of bed and into action.
"It's a serious business. He's made a couple of errors and the spotlight's on him - he has to respond.”
Despite Pardew’s hardline stance to Hennessey’s recent performances, the former Wolverhampton Wanderers stopper’s emergence has been a huge positive for the Eagles this season.
Palace’s goalkeepers have had to battle to earn the number one shirt - with both Alex McCarthy and Julian Speroni also at the club.
However, it seems that the position in between the sticks is now Hennessey’s to lose, and he will be hoping to have an error-free afternoon at the weekend.
Palace are set to take on Tottenham Hotspur tomorrow at White Hart Lane in their next fixture.
