The match at Wembley was marred by disorder as Hungary fans clashed with police, resulting in six arrests.
Concerns have been raised about the make-up of the 700 fans in the away end, with some of those involved in the trouble believed to be Polish supporters.
Asked why it was so easy for Polish fans, or anyone else, to buy tickets in the away end, a Hungarian Football Federation (HFF) spokesperson said: “That is really a question for the English FA. We were just provided with a link.”
The FA are not planning to change their policy of offering a web-link sales facility to visiting federations.
In agreement with the HFF, they facilitated the sale of tickets to fans wishing to attend Tuesday’s game. Due to quarantine rules, only 150 fans could travel from Hungary and the vast majority were UK-based. The FA do not screen supporters for matches at Wembley.
The FA will hope there is no trouble at the November 12 World Cup qualifier against Albania, whose match with Poland in Tirana on Tuesday was stopped for 20 minutes after their fans threw bottles onto the pitch. FIFA are investigating that incident.
The FA are also bracing themselves for the prospect of England having to play behind closed doors, with their disciplinary hearing into the trouble at the Euro 2020 Final due to take place on Monday.
July’s showpiece at Wembley was marred by crowd trouble as hundreds of ticketless fans stormed into the ground for the match between England and Italy. UEFA have since been investigating and a hearing is due to take place on Monday, with the outcome being revealed later that day or on Tuesday.
The FA face the prospect of England having to play behind closed doors as punishment.
Any stadium ban would be in relation to UEFA fixtures only, with the next round of games due to be Nations League matches in June.
