Brazilian legends Ronaldo and Romario on Monday indulged in a World Cup war of words as the former accused his compatriot of blaming him for a promise of free tickets for handicapped fans which has not materialized.

"It is deplorable to see Romario, once again, make me publicly responsible for things which are outside my remit," World Cup Local Organization Committee member Ronaldo wrote on his Facebook page.

Romario, 1994 world champion and now a lawmaker, himself took to social media in recent days to say 2002 World Cup star and record tournament scorer Ronaldo "publicly promised free entrance for handicapped people".
