The former Blaugrana President has accused his successor of lacking a clear vision for the club, and claims that the current administration is living off its "heritage"
Laporta, who presided over the Catalan club from 2003-2010, has never hidden his contempt for his successor.
In the latest attack on Rosell's character, Laporta has criticized the leaders of the Blaugrana for what he considers to be a lack of direction at Camp Nou.
"The path they have chosen is mistaken... I do not even know which path they have chosen, " Laporta told Il Catenaccio. "When I was President, I had no problem explaining to the world the Catalan cause."
"They are living in our heritage," added Laporta, who was in charge when Barcelona won its second Champions League crown in 2006.
Barcelona has won two further Champions League titles under Rosell, in 2009 and 2011.
