Rosell was arrested in May 2017 as part of a probe centred on audiovisual rights sales linked to Brazil's national football team.

Rosell resigned as president of Barcelona in 2014 after Spain's High Court began investigating irregularities in the way the club signed Brazilian player Neymar. He had denied any wrongdoing in that case.
