The 23-year-old Croatia full-back arrived at White Hart Lane from Manchester City claiming he had joined a club who had a better chance of a top-six finish.
However, a relegation dogfight has since followed and failings on the pitch led to the dismissal of Juande Ramos in October.
Since then, Harry Redknapp taken over as boss and despite amounting 30 points from 20 games and a Wembley final appearance in the Carling Cup, Corluka is not satisfied with Spurs' campaign.
"Before this season people were saying we needed to be in the top six, everything we achieve this season is not success because we are not there," he said. "We are not where we wanted to be."
BenchmarkSpurs face Champions League-chasing Aston Villa on Sunday, a club that Corluka expects his side to emulate next season.
"I would like to be in the position that Aston Villa are now," Corluka said.
"But we don't have an argument to say that - we are in the position we are.
"We have to do something and then we can say we will stay there but we are far from there now. We can't just talk about targets."
Meanwhile, Spurs boss Redknapp has become the latest person to sound out Ryan Giggs for the player of the year accolade.
He said: "I'd love to see Giggs get it. He's a great role model, great player and a fantastic person."
