De Boer and Dutch compatriot Louis van Gaal were both approached for the role, along with then Southampton manager Mauricio Pochettino.
Daniel Levy and the Tottenham board eventually went with the Argentine.
"If they wanted me, I would probably have said 'yes'," De Boer told Amstel Television 5.
"I was really close to a move to Tottenham, but they chose Pochettino.
"It's the same in a corporate company," he added. "Eventually the board will vote and they came out with Pochettino."
