Walcott had never played a Premier League game for Arsenal when he was chosen for the 2006 World Cup but at least The Ox has 26 appearances under his belt, even if 11 are as a sub.
Oxlade-Chamberlain told The Sun: "Theo told me he really enjoyed the World Cup even though he didn't play.
"He's been talking about the Euros and how exciting it will be.
"I don't really see us as rivals, we are friends. I've got a lot of respect for him as a person, he's very humble. I sit next to him in the dressing room, we play golf together and we even have the same hairdresser.
"We've always got on well, he always helps me and we have a good laugh."
