Eriksen admits Vertonghen key to Tottenham move
The pair were Ajax teammates before Vertonghen left for Spurs 18 months ago.
"I talked to Jan a few times before I came here," admits Eriksen. "He had nothing but good stories about the club.
"I was always impressed by Tottenham and the Premier League on television."
Of his time with Ajax, the Dane added: "I had to learn a lot when I came to Ajax. It was a new environment, a new club, but it went well. I tried to adapt quickly and eventually we became champion for three consecutive years."
