The 65-year-old is favourite to be named as the successor to Fabio Capello after the Italian quit last month with both fans and media trumpeting the Spurs boss as the man to lead England at the Euro 2012 finals.
Redknapp insists he has had no contact from the Football Association (FA) who have installed Stuart Pearce as caretaker until they decide on a full-time replacement.
Meanwhile Tottenham are reported to have offered him an improved contract and a large transfer budget.
"When you're in a club, you look for a striker and you sign him. When you're a national coach, you have to make do with what you have in your country," Redknapp said in an interview with French sports daily L'Equipe.
"If you don't have a striker, you just don't have one. And you almost never see the players. Two days a month: it's very difficult."
Asked if he would like the England job, he replied: "I'm not sure. I have a very good job at Tottenham and I like it here.
"But I don't know. Wait and see."
Redknapp joined Tottenham from Portsmouth in 2008, and has has turned the North London club into serious challengers for a top-four place in the Premier League.
They are currently third despite a three-match losing streak.
