Fighting broke out between the two sets of supporters in Amsterdam's red light district hours before Roberto Mancini's side suffered a 3-1 defeat to the Dutch giants
Fighting broke out in the city's red light district just hours before Roberto Mancini's side were beaten 3-1 by the Dutch club at the Amsterdam ArenA.
Large groups of opposing fans had been drinking throughout the afternoon before tensions spilled over prompting police to intervene, a spokesperson revealed.
Images of police in riot gear were aired on Dutch television, although the situation is reported to have been quickly resolved.
It is the third such incident in recent years after English and Dutch fans clashed before an international fixture in 2009 and prior to Manchester United's meeting with Ajax earlier this year.
