The Belgian international arrived at White Hart Lane from Ajax in the summer and has disclosed the reasons why he headed there and not to the Emirates Stadium after some heavy interest from the Gunners.
"(Arsenal's interest) was concrete, but they wanted me to be a controller in the midfield, an Emmanuel Petit-type," he told NUsport.
"I'm not afraid of competition, but the overall picture of Spurs appealed to me more.
"Ultimately, I just came to play at centre-back.
"Gareth Bale had to play left-back, but it did not work so he pushed forward and I moved to full-back.
"I see myself as a centre-back. I'm not agile enough to play against players like Nani and (Raheem) Sterling."
