The Cameroonian centre-back has proved an inspired signing for the Canaries who have now gone eight games without defeat.
"It makes a big difference for a player, especially somebody like me and my body," he said speaking on Talksport.
"I need to play week in, week out to get the best out of me.
"I've no regrets about leaving Tottenham. I am enjoying my time here and the results are good for us. The people around me at the club, the fans as well are lovely, so I am really happy to be here. I hope I can keep on scoring and helping to win games for Norwich."
