Barton and his OM teammates meet French league leaders Paris Saint-Germain - Beckham's new club - on Sunday but the QPR man says he is not going to worry about taking on the former Manchester United and Real Madrid star.
"Paris have a lot of big names and big players. Beckham is a big star off the pitch but on the pitch it's not a big worry," he said.
"He causes a lot less fear compared to when he played in the Premier League. It would be naive to concentrate on David Beckham."
