"It's a pleasure to win titles," said Ronaldo, a five-time Ballon d'Or winner, at the event.
"It's not easy to be top of the game for so many years. I am really proud, but without a team, great coaches and clubs it is not possible."
Ronaldo would also respond on Twitter , saying: "Couldn’t be happier with tonight’s award! As I’m about to celebrate my 20th year as a professional footballer, Globe Soccer Player Of The Century is a recognition that I receive with so much joy and pride!"
Guardiola was honoured for a managerial career which has seen him win league championships in Spain, Germany and England, as well as the Champions League twice.
