The Paulista club must defend their Copa Libertadores title this year and hope Barça defend their Champions League title in order for a rematch to take place in this years CWC.
"I can"t hide the fact that the year would be perfect if we beat Barcelona in a rematch in Club World Cup," Riberio told Lance.
"We want to win every title possible this year and return to the Club World Cup. If we go back to Japan, we will do everything to win, even if it’s against them [Barcelona] or anyone else we would have to face."
The next edition of the Club World Cup is scheduled to be played from 6th to 16th of December 2012 in Japan.
