Manchester City boss Pep Guardiola apologized to Ian-Carlo Poveda after the youngster did not make it off the bench against Southampton.
City beat Southampton and Sergio Aguero scored twice to put the club into Carabao Cup quarter-final.
Phil Foden, Tommy Doyle, Eric Garcia all started for the Blues.
"I'm so sorry to Ian-Carlo because he wanted to play as well but after 3-1 the game was not over and that's why we didn't make the substitution," said Guardiola. "After, with what happened with Angelino, John [Stones] came on."
