Euro 2012 may be looming at the end of next season.
But Walcott, 22, is taking nothing for granted after being a shock omission from Fabio Capello's England squad for the 2010 World Cup.
Walcott has returned to the fold since but is not getting carried away. He said: "I won't look too far ahead at the moment. I want to concentrate on Arsenal.
"It's important to have a starting place consistently for the whole year and then look forward to the summer.
"I don't want to be looking too far ahead and getting disappointed at the end of it."
