Manchester United fans defy orders and sing racist Lukaku song, club respond

Anti-discrimination body Kick It Out called for United fans to stop what they referred to as a "racist" chant but, according to numerous reports from St Mary's Stadium, it continued regardless.

The 24-year-old, who arrived from Everton in the summer in a deal that could reach £90million, scored his eighth goal in as many games, sparking further renditions of the song, along with a follow up from United fans.

United have now said again in a statement following the game against Southampton that they have a "zero tolerance" approach to behaviour of this kind.

"Manchester United has a zero tolerance stance on offensive chanting and behaviour," the statement read. "The club and player have been clear in asking for an end to the chant.

"The club is in discussion with the police and has asked for CCTV footage from Southampton and will try to identify those who disrespected the player's wishes not to sing the song."

Lukaku already has a couple of chants in his honour, although the one to the tune of the Stone Roses' Made of Stone has caused controversy as it references the size of his penis – a song the striker has previously said he hopes will stop.

"Great backing since I joined #MUFC," he was quoted as saying on the club's official Twitter account.

"Fans have meant well with their songs but let's move on together. #RespectEachOther".

The song, using the stereotype about black men, led anti-discrimination body Kick It Out to call for action.

The club also previously posted on social media ahead of Wednesday's Carabao Cup match against Burton that "action will be taken against any offensive behaviour", reminding supporters of the club's commitment to inclusivity.

Lukaku has become a firm fan favourite at Old Trafford with his goals inspiring Jose Mourinho's side to a strong start to the campaign.

United's victory over Southampton gave them a fine early-season record of five wins and a draw from their opening six games.
