“Now as players we have got to kind of give UEFA a chance to take that responsibility on board and deal with that situation.
“At this moment in time, full faith in UEFA.”
The game will be England’s first visit to Bulgaria since September 2011, when Ashley Young was subject to monkey chants as the visitors won 3-0.
The BFU was fined 40,000 euros ($44,000) by UEFA for “discriminatory” chanting and because fans threw fireworks.
Bulgaria were also punished by UEFA for “racist behaviour” when they lost away to the Czech Republic on June 7 and at home to Kosovo three days later in Euro qualifying.
For the England visit, UEFA has ordered the BFU to close at least 5,000 seats at the Vasil Levski National Stadium and display a banner that reads: “#EqualGame”.
