The veteran midfielder made a brief cameo during Sunday's Classique, and the France international was impressed with his technique and vision during Carlo Ancelotti's side's 2-0 win.
"Beckham is class. I think he has always kept his technique, his beautiful passes," Valbuena told reporters. "He is a great player and he has not lost his technique. I think he will bring a lot to PSG."
"But I also think he will bring a lot humanely, whether on and off the pitch. I think this is important and good for the Ligue 1."
Carlo Ancelotti's side currently holds a three-point advantage over Olympique Lyonnais in the Ligue 1 title race following the victory, in which Beckham was involved with the sequence that led to Zlatan Ibrahimovic's game-icing goal.
