The 28-year-old French defender, suspended for a year by Manchester City, is on trial in Chester, in the north of England, for eight rapes, an attempted rape and a sexual assault against seven women.
He denies the ten counts which relate to facts which allegedly took place between October 2018 and August 2021 at his home in Prestbury, Cheshire.
He faces life imprisonment.
Benjamin Mendy is on trial alongside another man, Louis Saha Matturie - unrelated to former footballer Louis Saha - prosecuted for eight rapes and four sexual assaults on eight women between July 2012 and August 2021. He also pleaded not guilty .
"The case is simple," prosecutor Timothy Cray told jurors.
"It doesn't have much to do with football. It's another chapter in a very old story: men who rape and assault women because they think they have power, and because they think they'll get away with it."
He described the two defendants as "predators ready to commit serious sexual abuse" on young victims who were "vulnerable, terrified and isolated", pointing out that the telephones of some women may have been confiscated when they went to the player's home.
The highly publicized trial taking place at Chester Crown Court, south-west Manchester, is expected to last more than three months.

Released in early January, he was placed under judicial supervision pending trial.
