Police have charged four people with drink, drugs and public order offences after Cardiff City's match with Wolverhampton Wanderers on Saturday.
Four men have been charged after the disturbances
Three men and one woman from south Wales have been told to appear before Wolverhampton magistrates on 20 March.
Another two men from south Wales were bailed pending further inquiries.
The second half of the match in Wolverhampton was delayed by 15 minutes after clashes involving Cardiff fans and police in riot gear at half-time.
Police arrested 17 men. Several officers were injured, one with a suspected fractured jaw.
The four bailed to appear before Wolverhampton magistrates are:
- Man, 42, from Merthyr Tydfil, charged with being drunk whilst entering a sports ground.
- Woman, 32, from Llanedeyrn, charged with being drunk while entering a sports ground and using words or behaviour with intent to cause harassment, alarm or distress.
- Man, 46, from Bridgend, charged with using words or behaviour with intent to cause harassment, alarm or distress.
- Man, 39, from mid Glamorgan, charged with possession of Class A drugs and using words or behaviour with intent to cause harassment, alarm or distress.
A 43-year-old man from Whitchurch arrested on suspicion of assault was bailed pending further inquiries, as was a 24-year-old man arrested on suspicion of violent disorder.
More than 300 police officers were on duty at the Molineux Stadium to prevent a repeat of problems at last season's fixture, which saw 30 arrests.
Seven people were arrested inside the ground and West Midlands Police said some trouble continued after the game, which Wolves won 2-0.
Cardiff City Supporters' Club spokesman Vince Alm said on Saturday he believed the problems at half-time could have been avoided. Mr Alm claimed riot police were used "too early".
But Inspector Chris McDermitt said officer had taken "prompt action" to reduce the risk of further disorder and risk of injury to officers and staff.
West Midlands Police are appealing for witnesses for information on what happened outside the game in the Camp Street area and coach park.
