Levy is seeking a new manager after the departure of Andre Villas-Boas yesterday.
"If it was my club I'd get Harry Redknapp and say there you go Harry. You would have a team within a few weeks," said Dunphy.
"Harry would have Joe Jordan with him, a good backroom team, the players loved him, and he would be my choice. My big question if I was a Spurs shareholder is why Harry isn't there."
