Arsenal teenage record-breaker Ethan Nwaneri had to change on his own before coming on against Brentford.
The 15-year-old is the youngest player to represent the club at the senior level, while he is also the youngest ever Premier League player.
Nwaneri came on in the last minutes of a 3-0 win over Brentford on Sunday.
According to The Telegraph, Nwaneri had to change alone due to child protection laws.
His age means it was not acceptable for him to change with the rest of his teammates.
At 15 years and 181 days, he has surpassed Liverpool’s Harvey Elliott as the youngest Premier League player ever.
