Max Dowman is old enough to play in the Premier League - but not to get changed with his team-mates.
The winger continued to show why he is one of the top-rated young players in the country when he made his Premier League debut at 15 years and 234 days on Saturday against Leeds United.
The appearance made him the second-youngest player to represent the club and the second-youngest to play in the Premier League - with team-mate Ethan Nwaneri holding both records.
His talent and his rise are no shock to anyone who has been around Arsenal for the past couple of years.
