The QPR manager said he was 'choked' to leave Spurs in 2012.
Harry Redknapp has been discussing his achievements at Tottenham from 2008-12.
In his first full season at White Hart Lane Redknapp helped the North Londoners qualify for the Champions League for the first time in their history, guiding them to a top four position at the expense of a Manchester City side bankrolled by the Abu Dhabi group.
The season after Spurs fell just short of another top four finish, though they did make it to the quarter finals of the Champions League, while in his final season at the club, Redknapp and Spurs were cruelly denied a place in the competition despite another fourth place finish because Chelsea won the tournament after finishing outside of the top four.
Many thought that the reason Redknapp left the club was because his Spurs side had blown a large lead over rivals Arsenal at the end of that 2011-12 season, with the Gunners pipping them to third spot in the league and thus avoiding the heartbreak as a result of Chelsea's penalty shoot out victory over Bayern Munich.
But the 67-year-old, now managing QPR, hinted that there is more to him leaving the club than is publicly known, while also stating he thought he was a striker away from leading to Spurs to a Premier League title.
“I think I could have actually won the league at Tottenham," Redknapp is quoted as saying to FourFourTwo. "If we had invested more at the right time, we could have done it. We were probably short of a striker.
“I know the reasons why [things didn’t work out], but they are personal. I enjoyed my time there, and to be honest I was choked when I had to leave."
One famous transfer window when Spurs were battling it out at the Premier League summit saw them sell Roman Pavlyuchenko and bring in French veteran Louis Saha on a free transfer. One year earlier Spurs reportedly spurned the chance to sign Luis Suarez.
The West Ham legend was disappointed to leave the Lilywhites, but takes satisfaction that the club's most successful period in recent years came under his stewardship.
“I couldn’t sit at home and sulk about it. It is life, it happens. They did what they wanted to do, but they haven’t been in the top four since me. I finished in the top four twice in three years.”
