He celebrates his 200th game as Portsmouth manager today and said: "It doesn't seem long since I last took over and we've come a long way.
"The club is going in the right direction, the young owner is building a new stadium, we have a new training ground on the way and we have a great squad of players.
"I doubt I would get offered the England job and I have my work cut out at Portsmouth."
Redknapp returned to Fratton Park in December 2005 and rescued Pompey from relegation.
He added: "We went into the next season as a favourite to go down, won our first game against Nottingham Forest and didn't look back.
"To be sitting sixth, where we are now, is a great feeling."
