The Ivory Coast international midfielder are being linked with Valencia and Sevilla.
He told the Spurs website: “I’m so happy to play at Tottenham, everyone has been so good to me and that’s the players, the staff and the fans. They love me and I love them.
“The first season in England isn’t easy but every week I’ve played, I’ve watched, I’ve learned. Now I’m very, very confident. It’s not easy because I’m a more defensive midfielder but I want to score three or four goals next season!
“The first couple of months were difficult, but everyone gave me so much confidence and the fans were part of that. I can remember the first time I heard them sing my song – their support meant so much to me.”
