The Kiwi is a £6 million target for Arsenal.
But the 25-year-old is refusing to get carried away with all the speculation and insists his main priority is to ensure West Ham enjoy another successful season.
He said: "I think a good season for West Ham would be having a good cup run and getting to the final.
"It would be nice to get back to Wembley. We've played there once in the playoff finals and it was a good day out. We are getting closer and closer but we know it is going to be difficult.
"Obviously, as captain of the New Zealand side, I would love to take them back to another World Cup and it would be brilliant for me personally."
