"I considered their offer long and hard. I see Tottenham as a very stable club, and they are only getting better," he told
FourFourTwo.
"They give young players a chance and I see Mauricio Pochettino as a manager who really improves young players. I like the kind of football they are playing. I think it would have suited my game."
But De Jong says he eventually decided against a move to Tottenham out of loyalty to Ajax, believing he still owed the Dutch club a further season.
"The moment wasn't right," he added. "I wasn't finished at Ajax, as I hadn't yet played a full season in my own position. I was also injured in that period, so I was thinking, 'Not yet'. I felt I should stay for another year at Ajax, or perhaps longer."
