Racist abuse marred the Euro 2020 qualifier between Bulgaria and England with the match in Sofia twice halted by the referee.
English Football Association chairman Greg Clarke, present at the Levski Stadium, said it was "probably one of the most appalling nights I have seen in football".
England manager Gareth Southgate informed the Uefa delegate after the first incidents with monkey chants aimed at England's three black players: Tyrone Mings, Raheem Sterling and Marcus Rashford.
A public announcement was made, with play stopped minutes before half time.
The abuse continuedin the second half with the Group A match, which England went on to win 6-0, again temporarily suspended by the referee under a three-step Uefa protocol for tackling racist abuse, which also included supporters making Nazi salutes.
In the match, England led 2-0 through early goals from Rashford and Ross Barkley. England quickly made it 3-0 with Barkley again on target before a second stoppage, with Croatian referee Ivan Bebek holding discussions with players and coaching staff from both sides.
Sterling then netted twice either side of half time before Harry Kane rounded off the scoring to take England to the brink of qualification.
