The Football Association is yet to begin its search for a new coach to succeed Fabio Capello, admits chairman David Bernstein.
Capello is due to stand down from his position after the 2012 European Championship if England qualify.
But Bernstein told the Leaders in Football conference: "It is not something on our agenda at the moment.
"We are completely behind Fabio. You cannot be half-pregnant with these things."
A report on Wednesday suggested some FA officials were open to the idea of Capello remaining as England boss beyond the tournament in Poland and Ukraine.
But Bernstein rejected the idea, joking: "I love the media. They are amazing, aren't they? One day he is going next week, the next day he is staying for 20 years.
"The position is very clear. He is our manager until the end of the European Championships. That is it."
Capello took over from Steve McClaren following England's disastrous Euro 2008 qualifying campaign.
The Italian led his team to the 2010 World Cup in South Africa but they were eliminated in the second round after a 4-1 defeat by Germany.
Capello insisted he would remain in charge until after Euro 2012 and England sit top of Group G ahead of Friday's decisive qualifier in Montenegro.
"You need to be completely behind your manager," said Bernstein. "We are supporting Fabio on Friday and hopefully right the way through to the Euros."
The FA has stated the next England coach should be homegrown, with Tottenham boss Harry Redknapp strongly linked with the role.
