Brazilian soccer star Dani Alves -- who's been detained in Spain since January when a woman accused him of sexually assaulting her in a club -- testified Monday he didn't assault anyone, but rather had consensual sex with the alleged victim.
According to the Associated Press, Alves testified there was a mutual attraction between him and the woman he's accused of sexually assaulting at a Barcelona nightclub on Dec. 30.
Alves initially denied any wrongdoing when the allegation was first made ... saying he didn't have sex with the woman, apparently fearing the admission would jeopardize his marriage.
