Beckham, 36, joined Barton in France when he signed for PSG after leaving Los Angeles Galaxy, and the two are set to face off in the league on Sunday.
At the time of Beckham’s arrival Barton expressed his delight that such a big name had come to Ligue 1, but he has since taken the line that the former Manchester United and Real Madrid midfielder was signed for commercial and not entirely sporting reasons.
“PSG have lots of big names and great players,” the outspoken on-loan QPR midfielder said. “Beckham is a big star off the pitch but on the pitch, to be honest, he’s not a major worry.
“He triggers a lot less fear than when he was playing in the Premier League.”
Barton has endeared himself to Marseille supporters since leaving his homeland, where he is a divisive figure due to his on-field antics and complicated off-field persona, both of which have been tainted by outbursts of violence.
Indeed, his character appears to suit a combative Marseille side who, while not boasting the riches of PSG, are five points behind them and able to land a double blow to their bitter rivals in back-to-back league and cup matches.
“If we take maximum points in Paris and we do the same in the French Cup that would make a big difference,” Barton added.
“We’ll be back to two points, and then they (PSG) have to play Valencia (in the Champions League). This week we can change our season.
“Everything changes if we win these two matches.”
