( CNN ) -- Barcelona 's money problems are worse than expected , according to the Spanish champions ' financial vice-president Javier Faus . A new audit by accounting firm Deloitte revealed that the Catalan giants actually made a loss of €77.1 million ( $ 100 million ) for the 2009-10 season , Faus said in a statement on the Barca website on Tuesday . The previous board had announced the club was €11 million ( $ 14 million ) in profit up to the end of last month , when president Joan Laporta stood down to be replaced by Sandro Rosell . `` The accounts submitted on June 30 do not reflect the true picture of the club , '' Faus said . Deloitte 's audit showed that income had been overstated by $ 47 million and expenses understated by $ 61 million . With an $ 89 million operating loss , Deloitte also found $ 14 million in further financial expenses to be countered by $ 3.9 million after-tax profits . Net debt has risen to $ 573 million from $ 427 million a year ago , while gross debt is now $ 716 million . Barcelona had to take a loan of $ 200 million after struggling to pay player wages last month , and -- after signing Spain striker David Villa for $ 50 million -- sold defender Dymtro Chygrynskiy to Shakhtar Donetsk and let high earner Thierry Henry join New York Red Bulls . `` There is a structural problem . The sporting excellence in the last few years has not been reflected in economic excellence . The new board 's goal is to bring economic excellence alongside sporting excellence , '' Faus said . Part of the problems lay in the bankruptcy of broadcaster Mediapro , with Barca claiming the club is owed $ 49 million by new rights-holder Sogecable . Meanwhile , Spanish rivals Real Madrid have allowed highly-rated young fullback Marcos Alonso to join English club Bolton . The left-back , 19 , has agreed a three-year contract , having made only one first-team appearance as a substitute in April after coming through the youth ranks . He follows veteran stars Raul and Guti in departing the Bernabeu this week .
Spanish champions Barcvelona lost $ 15 million last season according to new accounts . Outgoing board had said the club had made a profit of $ 14 million for the same season . Financial vice - president Javier Faus says previous accounts did not show true picture . Real Madrid let young star Fernando Alonso join English club Bolton .
