Punches were reportedly thrown between a Manchester United and Everton fans at a service station during their journey to London for today's FA Cup semi-final at Wembley.
A video has been uploaded onto Twitter showing at least three men involved in a brawl at Cannock services in Staffordshire at around 11am.
The footage was uploaded by an Everton supporter, who tweeted: "Manc bastards."
According to The Mirror, a Staffordshire Police spokesperson has confirmed that officers were called to an incident at the service station, but once they arrived the violence had ended and no arrests were made.
Fifty-seven coaches transporting football fans are due to come through the Cannock services throughout the day ahead of the FA Cup semi-final, which kicks off at 5.15pm.
