But after meeting with Spurs chairman Daniel Levy, the big defender was sold on Spurs.
Asked if Arsenal tried to sign him, Vertonghen said: "Yes. But I wanted to play here, so it was simple.
"I had already made my decision in my head that I wanted to play here. I'm not switching all the time, I make my decision and then I go for it.
"Tottenham came at the right moment for me and gave me a good feeling. I talked with Rafa van der Vaart and they invited me here and gave me the best feeling in the world.
"I hope we can win a prize. I think the main aim is maybe for Champions League qualification.
"We were always under pressure at Ajax - we were expected to win every game. I am used to it. We have a strong team here and the results will come. I am confident about it."
