The Football Association has called the fans involved in disturbances in Porto an "embarrassment" to the England team.
The condemnation has been echoed by the National Police Chiefs' Council (NPCC) football policing lead who declared the loutish, stag-do minority are threatening to ruin the Nations League for everyone.
Instead of focusing on Thursday's semi-final with Holland, the build-up is being dominated by fan behaviour after another night of disruption in Porto.
England supporters clashed with Portuguese police and were seen hurling bottles, prompting some local families watching the hosts' match against Switzerland in a fan zone to flee with their crying children.
