Manchester City defender Martin Demichelis has signed a one-year contract extension . The Argentina international was approaching the end of his previous deal but has now committed until the end of the 2015-16 season . Demichelis , 34 , has become an important member of City 's defensive unit after an initially shaky start following his move to the Etihad Stadium in September 2013 . Martin Demichelis ( left ) has signed a new one-year deal with Manchester City . ' I want to say that I am really proud and happy to have extended my contract for another year , ' Demichelis told the club 's official website . 'Manchester City is a club with a lot of ambition . We want to grow every year . 'When you get to hold a trophy , it 's the best feeling for any player . ' I want to say that I will fight for this club and for my team-mates until the end of my contract . I will fight to try and win titles . ' Demichelis worked with City manager Manuel Pellegrini at River Plate and Malaga and followed the Chilean to Manchester from the Spanish club via a brief , appearanceless , stint at Atletico Madrid . He also had a successful nine-year spell at Bayern Munich earlier in his career and was a member of the Argentina side that reached last year 's World Cup final . His early appearances for City were not impressive but he improved considerably after the nadir of a red card in a Champions League loss to Barcelona in February last year . Demichelis overcame a shaky start to his City career to establish himself in the back four . He played a key role in the season run-in that culminated with title success and he has made 30 appearances this season . Demichelis says he is now settled in England and has not even ruled out looking to stay beyond his new deal . He said : 'We are happy here - my wife and son are happy here . We are trying to improve our English and I think that 's a good thing for our future . 'At this stage I am enjoying playing week to week - you can never say what can happen in the future . ' Demichelis follows Joe Hart , Vincent Kompany , David Silva , Sergio Aguero , Samir Nasri and Aleksandar Kolarov in committing to the club over the last year . Discussions with another player out of contract at the end of the season , James Milner , remain ongoing . The England international has been linked with a move abroad in recent days but Pellegrini has often said they are hopeful new terms can be agreed .
