The 23-year-old is yet to feature in the league for the Magpies, raising questions over just why Pardew brought the striker to St James' Park in the summer.
But the Newcastle boss says he is picking up in training and 'improving,' although he still needs further work.
“We’re trying to build him, physically and mentally,” Pardew told the Shields Gazette.
“The Premier League is different to what he’s been used to. He’s picking up in training and is improving.”
It appears Newcastle's clash with Queens Park Rangers later today is a step too soon when it comes to Ferreyra's debut but Pardew seems pleased enough with the forward's progress that a chance could present itself shortly.
If that debut does not come in the following weeks, however, Ferreyra may have to go down as a signing that should never have been made.
Striking counterpart Ayoze Perez looks to have adapted to English football much faster.
