Seven police officers and two horses were injured in disturbances outside Goodison Park after Everton's FA Cup clash against Millwall.
A number of police vehicles were damaged
Although rival fans were kept apart, several hundred Everton supporters clashed with police outside the Blue House pub and nearby streets.
Six people were arrested and a number of police vehicles were damaged.
Merseyside Police said it was extremely satisfied with the policing operation and commended the officers involved.
Hundreds of officers from across Merseyside were drafted in to police the streets around Goodison Park on Wednesday night. There were also 28 horses, including eight from Lancashire.
Despite earlier reporting "no major incidents of disorder", the force said on Thursday that there had been clashes in Spellow Lane and County Road.
None of the officers were seriously injured, though one of the horses suffered cuts and has been treated by a vet.
Asst Ch Con Bernard Lawson, said: "It is clear from the atmosphere last night that there are still people parading as genuine football fans, who in fact are intent on hooliganism.
"Hooliganism has not gone away. It is only through the dedication and bravery of officers performing their duty that the situation remained under control."
Everton won the game 1-0 to progress to the fourth round.
