The duo found themselves dropped by Alan Pardew after the Toon boss deemed their attitudes weren't deemed good enough behind the scenes.
Bernard told the Evening Chronicle: "They are two players who can provide Newcastle with the one thing they lacked last season - a killer pass into the box.
"On their day they are top-notch Premier League players.
"But they have not been given a chance.
"Marveaux is a fine winger and Hatem Ben Arfa will win you games if he plays week in, week out.
"It's such a waste of talent."
