Manchester City manager Mark Hughes has made the experienced Brazilian Sylvinho his seventh summer signing.
The 35-year-old left-back, who spent two seasons with Arsenal earlier in his career, moves to Eastlands on a year-long contract.
Sylvinho will provide competition for first-choice left-back Wayne Bridge as Hughes continues to mould a squad together that he hopes will be good enough to challenge for a top-four spot in the Premier League.
Hughes said of the player: "Sylvinho has a wealth of experience at the very top level, having represented Brazil and played for some of the very top clubs in Europe.
"When the chance presented itself to bring him to Manchester City as a free agent I saw it as representing excellent business for us.
"Sylvinho won the European Cup last season at Barcelona and he will strengthen our defensive options."
Meanwhile, City are close to completing the signing of Everton defender Joleon Lescott.
Hughes has already signed Emmanuel Adebayor, Gareth Barry, Carlos Tevez, Kolo Toure, Roque Santa Cruz and Stuart Taylor this summer.
