The 20-year-old, who recently joined the North Londoners from Bolton, played the full 90 minutes of the 2-1 win over the MLS All-Stars late last week and drew praise for his composed performance.
He told Arsenal.com: "It was a bit crazy, especially when there was the national anthem and fireworks, I was thinking 'this is crazy'.
"But I really enjoyed it, playing against the likes of Kaka, Pirlo and Drogba was a great experience for me personally.
"I was definitely pleased with my performance. It's the first one under my belt which helps you get settled and build your way into it. Hopefully now I can show the fans what I'm about."
