“We have a strong policing operation in place and will be taking positive action to ensure that it’s a safe and enjoyable family event, for true fans to come along and cheer on their team.
“Today we are warning those planning to come along to get involved in violence and disorder that this kind of behaviour will not be tolerated and we will take the strongest possible action against anyone found to be involved.
“It is worth noting that the vast majority of those attending sporting events are genuine fans, who join us in condemning those responsible for disorder.
“There is no place for this kind of violence and disorder around what should be an enjoyable, family friendly activity, supporting your local team."
