Debuchy made his Newcastle debut in Saturday's 0-0 league draw at Norwich City and Pardew is confident the full-back will soon be showing what he is all about.
"In his first 10 minutes he was a little bit starry-eyed, but then he settled down," Pardew told the Newcastle Chronicle.
"You are going to see more quality from Debuchy in home games particularly.
"He is very good offensively. We restricted his movement because it was his first game, but he will grow into that role. He will grow into the jersey."
