Mikel Arteta's teenage son Gabriel was pictured in Arsenal training during their pre-season tour of America on Monday.
The Premier League side are undergoing preparation for the new campaign at a training camp in America.
The Gunners drew 1-1 against German side Nurnberg in their first pre-season friendly last Thursday, before they take on the MLS All-Stars a week later.
And in a surprising development, Arteta's son Gabriel, just 14 years old, was spotted at Arsenal's training session open to the public on Monday.
Gabriel wore a red Arsenal training shirt used by other coaches, hinting he is there as part of the coaching staff rather than training as a player.
