The highly-rated teenage midfielder will spend a few days training with the Gunners and is determined to make an impression.
He recognises that this stint in London is more about gaining experience than trying to earn a deal, but he would love to make the move to Europe permanently at some point in the future.
"I'm anxious for this new stage in my life," he told Globo Esporte.
"I'll spend a week at Arsenal. It will be cool, I hope I enjoy it.
"Of course I have the dream of playing for a European club, but everything has its right time. It will be a good experience. I want to learn."
Indio admitted he was a particular fan of Theo Walcott, adding: "I like him a lot. His style of play is very fast, which pleases me."
