After suffering a 4-0 drubbing at the hands of Bayern Munich in the Champions League, Barcelona will earmark 50 million euros or $65 million to buy new players and bring in new faces from its B squad.

"We will make four or five signings," Barcelona vice president Josep Maria Bartomeu said. "We must shake up the squad. We will bring in players from Barca B. There are certain positions that need to be strengthened."

Barcelona could use the money to lure Inter Milan keeper Samir Handanovic, Borussia Dortmund center-half Mats Hummels or Brazilian striker Neymar.

"The signing of Neymar is not done," Bartomeu explained. "Barca do have an interest in signing him. If he has not come yet, it is because he has a contract with Santos and we have no news that he wants to leave."

At the same time, Bartomeu also announced that coach Tito Vilanova will stay in charge next season.

"Tito will continue next year," Bartomeu told Catalunya Radio. "He has a contract, and we have faith in him. It has been a difficult year for Tito, as a coach and as a person, but despite all this his management has been good."

Vilanova and sporting director Andoni Zubizarreta could also get funds to spend should buyers be interested in David Villa, Alexis Sanchez, Alex Song and perhaps even Cesc Fabregas.

Meanwhile, Bartomeu said he had not given up hope of overturning Bayern's four-goal advantage in Wednesday's second leg at the Camp Nou, given the quality that Barca possess.

"Barca are excited about making a comeback in the tie," he said. "They are capable of anything - they are extraordinary. I know it is difficult to come back from four goals down, but surprises happen in football."
