The 28-year-old has not played for his country for three years, but has scored in his last three matches for Everton.
"Aaron has not been invited so five out of those six is not bad," said Martinez.
"Aaron is a very proud man and he will be very proud of representing England again but I don't think that was the drive for him reaching the level he has.
"I think the drive was to try to earn a place in the team and clearly he has given a lesson to everyone with how to behave in that role. He is a winger with a lot of experience and has the quality to get away from defenders but his defensive qualities are very strong.
"He will be ready if he needs to help England but at the moment he needs to concentrate on keeping the level of his performances he has shown in the last three games which has been the best consistent form he has had at Everton."
