Soldado struggled for goals at Spurs but was a popular figure among the White Hart Lane faithful.
Soldado, who was sold to Villarreal last summer, is preparing to face Liverpool in the semi-finals of the Europa League on Thursday.
The Spaniard, who cost a then club-record £26 million in 2013, found life tough at White Hart Lane - scoring 16 goals in 76 appearances.
But even when he wasn't scoring - or even playing - the Spurs fans would sing Soldado's song: "He came from sunny Spain to play at White Hart Lane."
However, the "incredible" backing he received only made things worse.
"I don't regret it at all, far from it, but I wanted to give a lot more than I gave in England," Soldado told the Mail.
"The affection that people showed me from the first day to the last was incredible. Even though I was not scoring goals and not starting games if I got off the bench (to warm up) their first reaction would be to sing my song.
"In the end that made it even more infuriating - to receive such support and yet be unable to repay it by making those fans happy."
Soldado, who broke David Villa's minutes-per-goal record during his time at Valencia, has become more of a provider than a goalscorer since his return to the Costa del Azahar.
The 30-year-old has scored eight goals in 41 appearances for Villarreal but has contributed 13 assists, with strike partner Cedric Bakambu stealing the headlines this season.
The DR Congo international has found the net 22 times and counting since arriving at El Madrigal from Turkish side Bursaspor last summer.
