Zamora says he is not thinking of the Three Lions and a chance to go to this summer's World Cup.
The ex-West Ham and Brighton hitman said: "I don't think that far ahead. Honestly, not at all. We have got so many games now that you do not get a chance to think about anything - let alone anything like that.
"I've now got 18 goals, which I am very pleased with. I'm not sure what the difference is from last year.
"Maybe I have stayed higher up the pitch.
"I'm lucky enough to have Zoltan Gera playing with me. He does that defensive role that I did a lot last year, in and around the centre of midfield.
"That gives me a chance to save a little bit more energy and stay high up the field."
