Six people were arrested after Manchester United and Leeds fans brawled on the streets prior to the first game at Old Trafford this season.
Footage shared on social media showed rival supporters fighting around the Deansgate area prior to the lunchtime kick-off on Saturday (14 August).
In one video, groups are seen throwing chairs and bins in the melee.
Greater Manchester Police has since confirmed that five arrests were made in relation to public order offences and one on suspicion of drug offences.
The rest of the game, which United won 5-1, reportedly passed without incident.
Chief Superintendent Stuart Ellison said: “Despite isolated incidents of disorder in the city centre prior to kick-off, today’s events at Old Trafford largely passed without police incident and I would like to thank the majority of the public for their cooperation throughout the day.
“There were many challenges around today’s operation, and our officers were working extended hours to help ensure that events passed safely and without significant disruption for the wider public going about their weekend activity.
“Work has begun immediately, in conjunction with football investigating officers from both Manchester United and Leeds United, to identify offenders of other incidents of disorder so that we are able to bring them to book for their mindless actions.”
More than 75,000 fans packed into Old Trafford for the fixture – the first time the stadium has held such a crowd since the original lockdown.
Bruno Fernandes scored a hat-trick during the rout of Leeds, with Mason Greenwood and Fred also getting on the scoresheet.
