El clasico: Former Barcelona president Sandro Rosell could attend Real Madrid clash hours after release from jail

The former Barca president has spent nearly two years in prison awaiting full trial over money laundering charges

Former FC Barcelona president Sandro Rosell will be released from prison on Wednesday and could attend el clásico hours later, his lawyer has admitted.

Rosell is expected to be set free from custody pending his trial on money laundering charges, having already spent 21 months behind bars.

Court officials in Madrid said Rosell will be released after his trial session in the Spanish capital on Wednesday, meaning Rosell will be just miles away from Real Madrid's Santiago Bernabeu stadium where Barcelona hope to continue their good record in the Copa del Rey.

The first leg finished 1-1 at the Nou Camp, and Rosell's lawyer Pau Molins revealed he hopes Rosell will be able to see a Barca win in Madrid.

"We will see if there is enough time and at what time he can be free.

"He is now a free man and clearly he could go [to the clásico] if he has a ticket or if someone invites him."

Rosell is unlikely to struggle for tickets as he still counts on support from senior figures at the club he left behind.

Current Barcelona president Josep Maria Bartomeu wrote on Twitter that it was the end of a completely unjust situation.

"Free and surrounded by their friends and family, they will better be able to defend their innocence," Bartomeu said.

Rosell has been in custody for more than 21 months after being accused of misappropriating funds coming from the sale of TV rights and the organisation of friendly matches featuring Brazil as well as from a sponsorship contract between Nike and Brazil. He is also charged with forming part of a criminal organisation.

The former Nike executive in Brazil, who presided over Barcelona from 2010-14, denied any wrongdoing when he testified before a judge on Tuesday.

Defense lawyers had made several requests to have Rosell released, saying it was unfair to have him in custody for so long without being convicted of any crimes. The previous requests had been denied because judges deemed Rosell a flight risk because of his connections abroad.

Rosell's former partner, Joan Besoli, will also be released.

Spanish media said friends and family members loudly celebrated the news when it was announced outside the courtroom.

The judge said in the ruling that Rosell and Besoli must turn in their passports and remain in Spain. They also must report to a police station every 15 days.

Rosell's trial, which began on Monday, is expected to last 10 days with different sessions through March.

Spanish prosecutors are seeking an 11-year prison sentence for Rosell, plus a fine of nearly 60 million euros ($68 million).

Prosecutors say he helped launder nearly 20 million euros ($22 million) related to commissions for Brazil matches during the time embattled Brazilian soccer confederation president Ricardo Teixeira was in charge.

Teixeira, a former FIFA executive committee member, was indicted by U.S. authorities in 2015 as part of the soccer corruption scandal. He has also been investigated by Brazilian authorities.

Three other people, including Rosell's wife, also have been charged in the case in Madrid.

The charges against Rosell are not directly related to his time as Barcelona president.

The 54-year-old Rosell is also involved in a separate case related to Neymar's transfer from Brazilian club Santos to Barcelona in 2013. Corruptions charges have been brought after a Brazilian investment group said it received a smaller compensation because part of Neymar's transfer fee was concealed by those involved.
