Football Association chief executive Brian Barwick insists he is not worried about the number of managers ruling themselves out of the England job.
Barwick said: "I'm not deterred - I'm determined to get the right person, the English footballing public is demanding that and it's my job to make sure we get that right."
He added that he understood the reaction of those fans who booed England players.
"We know that England fans are very disappointed and feel let down," said Barwick.
"I can't support people being booed but they pay their money and if that's they way they wish to express it, I can understand it.
"I think a huge part of what comes next is managing the intensity of the occasions, we have to make sure the players go on to the pitch feeling really good about themselves.
"Something I can bring to the party is how we can better manage that."
