Pardew knows Toon fans are concerned with the lack of signings.
He told the Sunday Sun: "You could argue that we should have gone out and spent (more) money on players, but then if it didn't work out that would have been a bigger criticism. We spent the money wisely and I think our fans should be thankful for that.
"Graham Carr did a tremendous job in targeting players and we have done our best to develop the ones we already have, and we think there are one or two at the club that the fans haven't seen yet.
"So I think we should be thankful for what we've got. We have a competitive squad.
"I have no problem with these radio debate shows, I really don't.
"I do think they tend to lean on the negative rather than the positive.
"You have to look at the bigger picture.
"We had a fantastic season last year and this time we've had two European games and two international breaks; the season hasn't really got going."
