England reached the latter stages of the competition after beating Croatia at Wembley on Sunday to top League A Group 4.
But there are now grave concerns that thugs could head out to Portugal and wreak havoc and take headlines away from the pitch.
The FA are ready to meet Portuguese police to work out strategies to deal with violence ahead of next summer's finals.
Last month in Seville, England fans ran riot before the Three Lions's game against Spain.
Despite Gareth Southgate's side triumphing 3-2, reports of supporters kicking off wing-mirrors and associated drunken violence took the gloss off the result.
MailOnline reports that "a number of options will be examined, including using the popularity of manager Gareth Southgate as an anti-yob weapon".
It could mean the manager himself sends out a message pleading for good behaviour from travelling England fans.
The possibility of alcohol sales being limited in Portuguese cities is also being considered.
Huge numbers of fans are expected to travel out to Portugal as the feel-good factor continues under Southgate's tenure.
ENGLAND WON'T WANT TO GO DUTCH
England could face either Holland, Switzerland or Portugal in the semi-finals of the Uefa Nations League.
And FA bosses might be hoping the Three Lions avoid a game against the Dutch.
Back in March, SunSport reported on violence before England's 1-0 win against Holland.
More than 100 arrests were made as fans clashed with police, hurled beer and taunted passers-by.
Trouble flared before the game with England supporters throwing beer bottles at police.
Riot cops then swooped in Amsterdam’s famous Red Light District and made 60 arrests after they “imprisoned” fans on a canal bridge.
England thugs circled around other motorists trying to drive down the road
But while many will be members of the official travel club, others will be heading out in the hope of bagging a ticket.
Others will simply be happy to be in and around the action, packing out local boozers to watch the action on TV.
SunSport reported last month on the ugly scenes played out in Seville, despite British police pleading for calm.
Footage showed noisy supporters kicking wing mirrors off vehicles parked in the street and aggressively circling drivers on the night before the Three Lions' clash with Spain.
One hooligan was filmed throwing a glass at a passing car in the centre of the Spanish city.
Riot police fired warning shots in the air as the situation threatened to spiral out of control, provoking a mini-stampede among some of the England supporters out in force.
