Twenty-five people have been arrested following violent clashes between Manchester City and Ajax supporters in Amsterdam on Wednesday.
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.
