Dani Alves has signed for Paris Saint-Germain and agreed a two-year contract with Unai Emery's men.
PSG confirmed they have signed the former Barcelona and Juventus star on Wednesday.
PSG will attempt to win back the Ligue 1 title from last season's surprise champions Monaco and Alves is their second signing of the transfer window after left-back Yuri Berchiche's arrival from Real Sociedad.
Guardiola had let right-backs Bacary Sagna and Pablo Zabaleta leave City at the end of their contracts and Alves appeared set to join the Premier League side, with his change of heart reportedly shocking the Premier League club.
Prior to his sole campaign at Juve, Alves had previously spent eight successful seasons with Barcelona, winning LaLiga six times and the Champions League on three occasions.
Sevilla and Bahia are his other two professional clubs, while he reached 100 caps for Brazil last year.
