Barton, who is currently on loan from Queens Park Rangers, has claimed that the former England captain "is not a major worry" on the pitch.
"PSG have lots of big names and great players. Beckham is a big star off the pitch but on the pitch, to be honest, he's not a major worry," Barton told reporters at a press conference.
"He triggers a lot less fear than when he was playing in the Premier League."
PSG currently top Ligue 1 by three points.
