Dowman is the latest young prodigy already making a name for himself at such a young age.
Born in December 2009, the midfielder has progressed through the academy ranks, and turns out regularly for the Under 15 side.
He recently made his bow against players five years older than him, in Arsenal's 4-0 win over Southampton.
Chidozie Obi-Martin netted a hat-trick and Louis Zecevic-John also scored, but fans were stunned to see Dowman handed a chance.
One said: "Best in the country for giving youth a chance. But even then, that's crazy young."

"We take a holistic view of the academy, pushing our players to excel," Wilshere told Arsenal's official website.
"Debut opportunities aren't handed out lightly, and Max has demonstrated over the past few months that he deserves this chance. There are others on the verge of stepping up as well.
"He handled the moment admirably, sending an important message to the team that when we introduce players, they possess the quality to contribute effectively."
