Ben Arfa is likely to be named on the bench for Saturday's game against Crystal Palace, but Pardew believes that it will take a number of impressive performances to earn support in the closing stages of a season interrupted by injuries and poor form.
"I've not lost patience with him but Hatem has to gain the trust of not just me but of our players and fans," the Newcastle manager told reporters.
"He has to show he's the real deal if he's going to play.
"Hatem needs a good finish to the season and he's aware of that for a number of reasons."
Ben Arfa has made 25 appearances in all competitions this season, scoring three goals.
