Walcott is confident that the knowledge gained in Poland and Ukraine this summer will stand a youthful, new-look England squad in good stead ahead of the 2014 World Cup in Brazil.
"There are a lot of young players who have gained good experience, me being one of them," he said. "Going into the next tournament, we will be better and there are loads more players who can get into this team as well.
"It is most important that we have a rest now because it has been a long season for everyone. I am not going to think about football. I think it is important to rest mentally, not just physically, because it's always up and down and can be tough."
