The Football Association has condemned the actions of fans who misbehaved in Amsterdam, where 100 England supporters were arrested on Friday.
On-field the Three Lions' last away game before the World Cup was a success, with Gareth Southgate's men defeating the Dutch 1-0 -- the first friendly win of his tenure -- but there were considerably less edifying scenes elsewhere in the city.
After trouble on Thursday evening, Amsterdam police confirmed that 102 people were detained on Friday, comprising of two Dutch fans and 100 Englishmen.
The police confirmed that 35 spent the night a cell and 94 were fined, with eight more still being questioned "mainly for violence against the police".
An FA spokesman said on Saturday: "We condemn the unacceptable scenes in Amsterdam. As was reiterated ahead of the fixture, we always urge supporters to respect our hosts and behave in a responsible manner.
"As ever, the FA will work in partnership with the UK Football Policing Unit to help identify those involved and we will sanction any England Supporters Travel Club member found to be responsible for disorder."
England manager Southgate had urged supporters to act respectfully prior to the match, but that plea was not heeded by all.
Social media offered some insight into the less wholesome actions of some groups in the city, while a portion of the 5,253 fans in the away end booed the Dutch national anthem.
"I heard some of the booing of the anthem which obviously isn't acceptable," Southgate said after the match.
"The rest, that's the first I've heard just outside before (coming into the post-match press conference). Without knowing the details... obviously it's not something I want to hear because most of all for us I think our players have represented their country really well tonight with pride and with some style.
"So, anything else that takes away from that performance for them would be a great shame."
The flare-ups in Amsterdam come a year after despicable scenes marred England's friendly against Germany in Dortmund.
The 1-0 defeat in March 2017 led the FA to clamp down on boorish behaviour, with lifetime bans from the England Supporters Travel Club (ESTC) dished out for the first time after two individuals were caught making Nazi gestures.
There were 27 members suspended in total for their behaviour in Dortmund.
The FA will review those caught up in trouble in Amsterdam to see if ESTC members were involved and punish them accordingly.
A number of England fans were expected to have bought tickets in the home end for Friday's friendly.
