Undercover racism spotters will report to Uefa from England’s Euro 2020 qualifier in Bulgaria.

Undercover racism spotters have been commissioned by Uefa amid heightened abuse fears during England’s Euro 2020 qualifier in Bulgaria, Telegraph Sport understands.

Three plain-clothed observers from the anti-discrimination network Fare will have live communication with the governing body to relay any reports of abuse.

England play the Czech Republic in Prague on Friday and then Bulgaria on Monday at the Vasil Levski national stadium, which will have a reduced capacity by orders of Uefa because of racial abuse during the games against the Czechs and Kosovo in June.

The FA said the players’ agreement was to follow the Uefa protocol that racial abuse is reported first to the referee, who calls for a stadium announcement, and if that fails to solve the problem, the players are taken off the pitch.

However, Tammy Abraham, the Chelsea striker, suggested that if the situation is particularly bad, the team will be led off by captain Harry Kane regardless of the protocol. Such a move would be unprecedented from an England team, although Gareth Southgate has said in the past that the players and staff would be prepared to take matters into their own hands if the situation required it.

The team were abused by fans in March in a Euro 2020 qualifier in Montenegro, for which the hosts were punished by a €20,000 (£18,000) fine and their next game being staged behind closed doors.

A Fare spokesman said: “Unfortunately we can not comment on the presence of our observers before the match for safety reasons as they work anonymously in the stadiums.”
