The 21-year-old has recently been linked with the likes of Real Madrid, AC Milan and Juventus.
“It’s flattering to be linked with some big clubs, but, as far as I’m concerned, I’m playing for a very big club and I can fulfil all my dreams at Spurs,” Walker told the Sunday Mirror.
“Why would I even consider leaving? It’s not even open to debate. I owe a debt of gratitude to the club and the manager, Harry Redknapp, and I couldn’t be happier and more grateful.
“Besides, I am not going to get carried away and I have a good group of people, including my agent, family and friends, who ensure I keep my feet firmly on the ground.”
