Porto goalkeeper Iker Casillas is a target for Major League Soccer franchise New York City FC, sources have told ESPN FC.
New York City, under head coach Patrick Vieira, are keen to strengthen their squad after a disappointing first campaign last season in MLS.
Manchester's City's sister club already have former Chelsea star Frank Lampard, Italian playmaker Andrea Pirlo and ex-Barcelona striker David Villa in their squad.
Sources have told ESPN FC that New York City have held a long-term interest in former Real Madrid player Casillas and they hope they can convince him to leave Europe for America
Casillas, who started his career at Real Madrid, made over 500 appearances for Los Blancos before his departure to Porto last summer.
