The Athletic player was named in the report alongside David De Gea and maintained his innocence, while Isco hit out against reports that stated he was also involved
Iker Muniain and Isco have released statements denying allegations the pair were involved in a sex scandal in 2012.
The Athletic attacker was named in a police report linking him with a witness statement accusing him and an unnamed player of sexual assault.
David De Gea was also connected to the case, as it was alleged that he organised the reported rendezvous, but the Manchester United goalkeeper assured the allegations were false in a press conference on Friday.
