Sigi, who joined from German outfit Hoffenheim for £8million, was widely expected to follow new Kop boss Rodgers to Anfield after starring on loan for him at Swansea last season.
But the goalscoring midfielder told The Sun: “Everything about Tottenham just felt right for me. Liverpool are also a fantastic club but if you look at where Tottenham have finished in the last few years, they finished above Liverpool.
“With a new manager, a new training ground and plans for a new stadium, I believe there are exciting times are ahead.”
He added: “I think everyone expected me to follow Brendan.
“But I had made my mind up to come to Tottenham and I’m happy with my decision.
“Brendan’s a fantastic manager, I enjoyed my time at Swansea with him and hopefully he will do well at Liverpool. I spoke to him briefly after I had made my decision.
“What I said to him after I told him I wasn’t going to Liverpool is between me and him. Obviously I owe him a lot. But in that sense it’s a new era for me.”
