Leicester City FC fans started a massive brawl and attacked beggars in Madrid's Plaza Mayor in the Spanish capital on Tuesday, in its tranquil central square at around 21.30, forcing police to intervene.
Some of the offenders have been sentenced to four months in jail.
Of the 70 involved, eight were sentenced by a duty judge in Madrid on Thursday, for public disturbance, and six of these were given another four-month sentence for actual bodily harm against police officers.
Their custodial sentences can be avoided if they pay a substantial fine, although the injured officers will be entitled to compensation.
Prison sentences of less than two years do not have to be served in Spain if they are for a first offence, but as six of the Leicester fans are charged with two offences, they would normally have to go to jail even for this short time if they do not pay the fines.
The following evening, defending champion Atlético de Madrid beat Leicester 1-0.
