First-half goals from Marcus Rashford and Anthony Martial were enough for Manchester United to secure a 2-1 derby win over Premier League champions Manchester City at Etihad Stadium – but the match was marred by reports of alleged racist abuse.

Rashford won and scored a penalty before Martial added a deserved second to send Ole Gunnar Solskjaer’s United into half-time in full control.

Pep Guardiola’s champions tried to rally after the break but United were equal to much of what they had to offer – and though Nicolas Otamendi scored a header late on to make it a nervy finish, the Red Devils saw out the result to seriously damage City’s title hopes.

United’s joy at the result was tempered by unsavoury scenes in the second half: United midfielder Fred was hit by a missile thrown from the crowd, while video footage appears to show one supporter making a monkey gesture towards Fred and Jesse Lingard.

English football’s equality and inclusion organisation Kick It Out said in a statement: “We have been inundated with reports of alleged racist abuse from a number of individuals during this evening’s Manchester derby.

“We will be contacting both clubs to offer our support and hope swift action is taken to identify the offenders.”

Man City have said they are “… aware of a video circulating on social media which appears to show a supporter making racial gestures”, and are “… working with Greater Manchester Police in order to help them identify any individuals concerned”.

Solskjaer told Sky Sports following the game: “I’ve seen it on the video. Fred and Jesse in the corner taking coins from the City fans first of all, so they’ve got to go away.

“And then there’s this not-so-intelligent fella chanting racist abuse towards my two players and I hope City and the authorities will deal with it, because he shouldn’t be watching football again. Not live, anyway.

“We have to stamp it out. We keep talking about it every single week and it’s not acceptable. He should not be allowed back into a ground. That’s how simple it is.” The home for trending sports news.
