Barton is looking forward to going toe-to-toe with the former England captain, but believes he trumps him in the looks department, if nowhere else.
He tweeted: "Really hope Beckham goes to PSG. Double header against them in French Cup and League back end of Feb at their place.
"He'll be great for French Football. Although, he'll remain 2nd best looking, Englishman in France. That'll hurt his confidence!"
Beckham has been without a club since leaving LA Galaxy last year, after winning the MLS Cup with the California-based club.
He confirmed earlier on Thursday that he was travelling to France ahead of the deal: "On way to Paris, excited. I will update you all later."
