"As soon as I knew they were interested in me, there was nowhere else I wanted to go," Bentley told a press conference on Thursday.
"I think we can do anything we want to, we've got a great manager and the level of player at Tottenham has risen.
"There's young talented players and it's all there if we work hard and give everything. It's up to me to perform and I'm excited by it.
"Working under someone like Juande Ramos should bring the best out of me, he can develop my game and push my game on to the next level.
"I want to be as successful as I can and I owe Tottenham a lot for paying such a big fee for me.
"I had my heart set on coming to Tottenham and I didn't really think about going to another club."
