Cole says his Anfield move was a career killer.
He revealed to cfuk: "I can only play for teams that I'm passionate about and I think that's what went wrong for me at Liverpool.
"I didn't feel a connection with the club or the place that I had at Chelsea and West Ham.
"Spurs was probably the best option because they were offering me a five-year deal and it meant I could stay in familiar surroundings.
"But I just couldn't do it, I just couldn't see myself pulling that Spurs shirt over my head.
"With the rivalry between Spurs and West Ham and Chelsea, it felt a bit mercenary."
