He told The Sun: "I had a good time (at Newcastle), yet felt I had hit a bit of a ceiling. The club and myself had gone as far we could."
"I felt I needed to develop quicker and Spurs could offer me that under Martin Jol. I have no doubts whatsoever that this has been the best move for me. I am thoroughly enjoying myself here."
Graeme Souness confirmed it was the midfielder’s decision and admitted Newcastle didn’t want to sell Jenas.
"Several of his mates are at Tottenham, which was always going be attractive for him. Even so, we were a reluctant seller."
"We bought Scott (Parker) to play alongside JJ. He is a young man on the fringes of the England team and has the potential to be a regular."
But Jenas opted instead to play alongside Michael Carrick at Spurs, and the rest is by the way as Newcastle United visit White Hart Lane today.
Spurs assistant coach Chris Hughton looked ahead: "I’d expect to see Newcastle line-up in a 4-4-2 formation on New Year's Eve. It's how they've played all season and with Michael Owen and Alan Shearer I can't see them approaching this game in any other way."
