Newcastle boss Alan Pardew is confident his squad is strong enough to compete in the Premier League despite a lack of signings on deadline day.
Newcastle's only acquisition this summer was QPR and France forward Loic Remy on loan.
"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 told the club's official website.
"Joe 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."
