Nocerino is on-loan from AC Milan.
He told Radio Deejay: "I hope this spell with help me get back into the Italian squad.
"One of the reasons I came to West Ham and to the Premier League is to play on a regular basis.
"My first objective is to play for West Ham and help the club move up the table.
"From that, if I am playing well and I get picked to go to the World Cup in Brazil, that will be an added bonus."
