Celtic have 'best fans in world' – Lennon
Neil Lennon was "not surprised" there was trouble in Amsterdam ahead of Celtic's Champions League game against Ajax on Wednesday night given the behaviour of the Dutch club's fans in Glasgow last month.
Eight police officers were injured in the violence in the city centre before the Hoops' 1-0 defeat at the Amsterdam ArenA with 44 people arrested, including 28 Scots.
Celtic responded to claims from Hoops supporters that they were poorly treated by opening an internal investigation and claimed their supporters were subjected to "a high degree of provocation".
UEFA opened an investigation following the Group H fixture between the two clubs at Celtic Park last month after the visiting fans clashed with stewards and police during the game.
Ahead of the Scottish Premiership game against Ross County in Dingwall today, the Parkhead boss said: "I am disappointed but not surprised, looking at what happened at Celtic Park.
"If there are Celtic fans who have been out of order and they are members or season-ticket holders then the club will take appropriate action, obviously.
"If the club's reputation has been damaged in any way I am disappointed with that but Celtic fans, I think, are the best in the world. But I think there is a culture at Ajax. I think Man United fans and Man City fans had problems recently so I don't think it is exclusive to Celtic.
"I am not going to point the finger at them (at Celtic fans) because I don't know what the facts are but our fans are exemplary."
