Barcelona presidential candidate Joan Laporta has accused rival Josep Maria Bartomeu of leading the club "to a very delicate situation".
Laporta, who was at the helm at Camp Nou from 2003 until 2010, confirmed this week that he will stand for election on July 18 "with the aim of making Barcelona a club for everyone again".
And the 52-year-old has taken a swipe at one of his opponents, with Bartomeu having presided over a tempestuous period marred by a transfer ban and legal proceedings over the deal to sign Neymar.
"We need your help more than ever to win. Now is the moment of truth," Laporta said to reporters on Friday.
"We want to rebuild a model based on Johan Cruyff, Unicef, Catalonia and La Masia. We know there are a lot of things happening in our country. Our candidacy has a special sensitivity to these issues.
"There are many differences with the candidacy of Bartomeu. His way of leading the club led it to a very delicate situation."
Laporta does, however, concede that he is not the favourite to be elected to lead the treble-winners forward.
"I do not see myself as favourite, we'll have to convince Barcelona fans that our club model is the right one," he added.
"It's normal that the former president has more options but polls give us chances, too."
