There were 28 arrests in the red light district of Amsterdam, as City and Ajax fans clashed in the streets.
City have a tough test ahead of them and look certain to join Newcastle in the Europa League next round.
Manchester City manager Roberto Mancini accepted it would take a "miracle" for his team to reach the Champions League knockout stages after Wednesday night's costly defeat at Ajax.Mancini: "It is very difficult to qualify now.
"It would be a miracle."It is my fault. I didn't prepare well for the game and I take the blame."I thought in one way and it was different. When you prepare in one way and it is a different game, it is difficult."We had more chances to score and in the Champions League you need to score. It is my fault, I repeat."We changed for five minutes to three at the back, but we always have 11 players."I don't think that is important - three, four, five, six or seven defenders."If someone wants that as an excuse then okay, but it's not the reason."
