( CNN ) -- Barcelona 's immediate footballing fortunes may be in some doubt , but the Spanish club 's members voted Saturday to approve a proposal aimed at securing its long-term future . Involved in a tense La Liga title race , locked in a Champions League battle with Atletico Madrid , facing a transfer ban due to alleged irregularities involving the signing of youth players , plus a tax investigation over the murky deal to buy Neymar -- it has been a testing season for the Catalan outfit . And the reaction has been one of defiance . Before Saturday 's 3-1 win at home to Real Betis , a big flag in the Camp Nou stated `` Do n't touch La Masia '' -- a response to FIFA 's punishment for infringing transfer rules relating to players under the age of 18 . Barca 's famed academy has produced a conveyor belt of talent , but the `` Espai Barcai '' proposal is deemed to be just as important to the team 's continued success . Some 118,000 members were called to vote after the Betis match in the club 's first referendum since 1950 , when it was decided to leave the Corts stadium and build a new one -- the Camp Nou . The turnout was not quite that high -- just under a third of the total . More than 27,000 members approved plans for a $ 725 million revamp that will extend the ground 's capacity to 105,000 people and develop the surrounding areas . Just over 9,500 voted against . The project is due to start in 2017 and be completed four years later , including the creation of a 12,000-capacity multi-sports pavilion and 5,000 new parking spaces . `` The members were voting for the future of this club , '' said president Josep Maria Bartomeu , who was appointed after Sandro Rosell stood down in the wake of the Neymar revelations -- the club later paid an extra $ 18.5 million in taxes after being hit with fraud charges . `` Days like today are when the world sees what FC Barcelona is and means , '' he added . `` The support for the New Espai BarÃ§a proposal has been extraordinary . It 's a huge project that will improve the club for years to come . '' Saturday 's win on the pitch kept Barca a point behind Atletico with six games to play , ahead of Wednesday 's second leg of the Champions League quarterfinal at Vicente Calderon , with the score 1-1 . Lionel Messi opened the scoring from the penalty spot in the 15th minute after Alexis Sanchez was tripped by Jordi Figueras , who in the second half diverted Adriano 's pass into his own net . Substitute Ruben Castro immediately reduced the deficit but Messi netted his 25th league goal this season after his 86th-minute penalty was blocked by goalkeeper Adan . Atletico stayed top with a 1-0 win at home to Villarreal thanks to Raul Garcia 's first-half header -- his 16th goal this season . Third-placed Real Madrid remained two points behind Barca following a 4-0 win at Real Sociedad , who stayed sixth . With star player Cristiano Ronaldo injured , record signing Gareth Bale took center stage with an opportunist long-range strike to put Real 2-0 up after Asier Illarramendi 's opener . Pepe then volleyed in from fellow defender Sergio Ramos ' headed pass , while Angel Di Maria sent substitute Alvaro Morata clear to wrap up a comfortable win ahead of the Champions League trip to Borussia Dortmund , with Real holding a 3-0 advantage . In Italy , Inter Milan 's hopes of qualifying for the second-tier Europa League suffered a blow as striker Diego Milito missed a penalty in Saturday 's 2-2 draw at home to struggling Bologna . It meant Walter Mazzarri 's fifth-placed team have not won for the past four Serie A matches . In France , Paris Saint-Germain guaranteed another season in the Champions League with a 3-0 win at home to Reims which put the Ligue 1 titleholder 16 points clear of second-placed Monaco with six games to play . Uruguay striker Edinson Cavani made up for the absence of injured star striker Zlatan Ibrahimovic by opening the scoring just before halftime , while Algerian defender Aissa Mandi netted two own-goals after the break .
