Sunderland loanee Amad Diallo has asked fans to change their chant about his manhood due it's "lack of respect".
The Manchester United youngster, 20, has begun to flourish in the North East, becoming a fan favourite.
But according to talkSPORT reports, a section of Black Cats supporters ignored his request against Millwall on Saturday.
Early on during the game, the chant - which includes a line about the size of his manhood - could be heard from the stands.
Diallo had previously stated: "Sunderland fans, I've had an amazing time so far and I love your energy.
"Hearing you sing my name is incredible, but we need to be respectful.
"Let's change the song and keep the noise."
Sunderland went on to hammer the South London club 3-0 as they move into the Championship's top half.
