"Of course," Bentley told ZOO magazine when asked if Champions League qualification was a realistic target this season.
"With the squad we have, we can do anything we want! And we've got an incredible boss.
"I don't like it when managers try to be your best mate; Juande Ramos is everything I want in a coach. He's tough and gets what he wants."
The former Blackburn player also revealed that he struggled for sleep in the days leading up to his move to Spurs.
He added: "People don't realise - or perhaps they do, as everything's dragged out across the media - how it affects your life.
"You have to relocate and make sure the girlfriend's cool. It becomes emotionally draining. Even when the bid was accepted, I couldn't sleep as I was too excited thinking about playing for the club.
"I wasn't even sure Tottenham wanted me! As a player, you can only voice your opinion and say "I want to go there".
"I was lucky, because lots of teams were interested, but Spurs were my team. And I wouldn't take "no" for an answer."
