The club's only senior signing was a season-long loan deal for Loic Remy from QPR, while the manager insists he is happy with his side's business, despite wanting two strikers
Joe Kinnear was appointed as Newcastle's director of football in June, with the 66-year-old adamant that he would improve the squad.
However, striker Loic Remy has been the club's only senior recruit after joining on a season-long loan from Championship side QPR in August.
Newcastle's sole permanent transfer saw them bring in 17-year-old midfielder Olivier Kemen from Metz, while prospective deals for Lyon striker Bafetimbi Gomis and England international Darren Bent - who joined Fulham on loan in August - failed to materialise.
"We are delighted to have brought Loic Remy to the club in this window and we believe he will form an exciting and effective partnership with Papiss Cisse," Pardew said in a statement.
"Joe [Kinnear] has worked hard on numerous targets, particularly an additional offensive player.
"However some of the options that were available within our financial means were not as good as the players we already had and there is no point bringing in new players unless they can improve us and take us forward.
"We did the majority of our business in the January window, signing five excellent first team players.
"With the strong squad we have we should all approach the season in a positive, optimistic frame of mind."
