Barcelona president Josep Maria Bartomeu has revealed that "when the Neymar case is over" the club will look into filing a lawsuit against the person who leaked the Brazilian's contracts, and possibly against the media outlet which published them as well.

Bartomeu said that the club has ruled out suing Jordi Cases "for damages" after his complaint led to Sandro Rosell's resignation, and he assured that the club has already spoken to him.

"We have evidence that [Cases] did not leak the contracts. When the trial ends, we will take the initiative. We know who did it," said Bartomeu, who believes that Real Madrid has been trying to draw attention to the issue because "it finds it hard to accept that [Barça] has dominated in recent years".

He does not know whether the company MCM – which has a financial dispute with the club over another issue, as announced on Twitter on Sunday – will join the lawsuit which Cases now intends to drop.

"We don't know, but it wouldn't surprise me. I'm seeing a certain animosity (from Madrid) towards Barça. It is hard for them to accept that we have two such dominant players as Messi and Neymar," he said.

He assured that the sums involved in the transaction were not released earlier for questions of safety. "The Neymar family asked us to keep it confidential, but for questions of their safety. The family is extensive and they live in a country (Brazil) with high levels of crime. That was the reason," he insisted.
