Everton boss Carlo Ancelotti explained the delay for Djibril Sidibe's substitution in victory over Crystal Palace.
The fullback was introduced off the bench early in the first-half following an injury to Theo Walcott but he was delayed coming onto the pitch because he had forgotten to put on his left sock.
"He forgot the socks," Ancelotti said.
"A new experience for me. Also for him, I think."
Everton ranout 3-1 winners on the day.
