FC Barcelona president Sandro Rosell presented his resignation Thursday during an emergency board of directors meeting at Camp Nou.

Rosell, who took the helm at Barça in 2010, stepped down a day after a Spanish court agreed to investigate allegations by a club member that the now-ex-president profited personally from the acquisition of Brazilian striker Neymar for a transfer fee of 57 million euros ($78.2 million).

The board voted unanimously for the club's senior vice president, Josep Maria Bartomeu, to serve the balance of Rosell's term, which ends in June 2016.

"In recent days an unfair and reckless accusation of misappropriation has resulted in a lawsuit against me in the National Court," Rosell said after Thursday's board meeting.

"From the beginning I have said that the signing of Neymar Junior has been correct and his signing has caused despair and envy in some of our adversaries," he continued, reading from a prepared statement.

"The Board of Directors is a team. And this team leads a project that has brought the Club great success. I don't want unfair attacks to negatively affect their management or the image of the Club. This is why I think my time here has come to an end," Rosell said.

FC Barcelona enjoyed considerable success during Rosell's 3 1/2-year tenure, winning two La Liga titles, a Champions League crown and a Club World Cup, among other triumphs. EFE
