Gunners fans were left amused to see their academy graduate picking up a booking even before his debut.
Taking to X, Aaron West wrote: "Imagine being so arsenal you get booked before even making your full debut. myles lewis-skelly is anointed."
An account named Men in Blazers posted: "Myles-Lewis Skelly has just achieved something remarkable at the tender age of 17: Received his first yellow card before even getting on the field to make his Premier League debut. What a future awaits."
A user named Shutts wrote: "It is absolutely VITAL that this Myles Lewis-Skelly never plays for Arsenal and leaves with more bookings than games. Genuinely the only important thing to come from this match."
A fan with the username inacio/isaac added: "Myles Lewis-Skelly yellow, you’re going down in the Arsenal history books son."
A fan page named Now Arsenal offered an explanation as to why the player was handed the yellow: "Michael Oliver has just booked Myles Lewis-Skelly for telling David Raya to go down injured. WHERE THE FUCK IS THAT IN THE RULES?"
