England face the Republic of Ireland tonight before travelling to South America to play Brazil.
Oxlade-Chamberlain, 19, is up for the latest challenge and told The Sun: "To finish the season on a high is positive for me and for Theo Walcott.
"The confidence from that can help us in the England games.
"The way we fought back when people doubted us showed that, with togetherness, you can go far. England, like Arsenal, have great players and on our day we can beat anyone.
"With Hodgson, we can do great things. To go away with England? It doesn't need any more motivation.
"As soon as you meet up, you get back in the swing of things.
"I can't wait to get out there."
