The Argentine defender believes the addition of his former Manchester City team-mate would be a huge boost to Manuel Pellegrini's men
Samir Nasri's quality would be a welcome addition to the West Ham squad, according to Pablo Zabaleta.
Former France international Nasri has been training with the Hammers in a bid to improve his fitness and earn a contract through to the end of the season.
Nasri last played a competitive fixture almost a year ago, in the Turkish Super Lig for Antalyaspor, and is preparing to return from a doping ban after he received a drip treatment at a Los Angeles clinic in 2016 while on loan at Sevilla.
