Dani Alves was arrested and detained on Friday, with the former Brazil, Barcelona and Paris Saint-Germain player accused of sexual assault.
Xavi was “in a state of shock” following news of former Barcelona star Dani Alves being arrested on suspicion of carrying out a sexual assault.
Brazilian right-back Alves was arrested in Barcelona on Friday after allegedly assaulting a woman in a nightclub bathroom.
The 39-year-old denied committing the crime when he spoke to Spanish station Antena 3 in early January.
Alves, who also played for Paris Saint-Germain and Sevilla, gave a statement to the Mossos d’Esquadra police force on Friday before prosecutors asked that he be detained and not granted bail.
He was held in prison during the investigation and his contract with Mexican club Pumas UNAM was terminated.
Xavi, a former Barcelona teammate of Alves, signed the defender for a short second spell at Barcelona last season.
At Barcelona’s pre-match press conference on Saturday, Xavi said: “It’s difficult to comment on a situation like this. I’m surprised, shocked, in a state of shock.”
“It’s a matter of justice. Justice will dictate anything.”
Alves became the oldest player to appear in a World Cup match for Brazil when he played against Cameroon in Qatar last month.
