Soldado departed White Hart Lane over the summer, after struggling to make an impression at the London club, and says that he is pleased to be back in his homeland.
The 30-year-old has scored twice in his first three matches for Villarreal, and admits that he is really enjoying his time in new surroundings.
"I couldn't have wished for a better welcome and on a sporting level, we have started well, which is the most important thing," he said in AS.
"Coming back has surpassed all of my expectations -- I couldn't have imagined that it would be as good as it has been so far. I was really keen to come back to Spain, and above all to a club which has everything it needs to do things well.
"We know we've got great potential in attack and in defence if we play as a team. The players who arrived over the summer are trying to get to know each other so that we can enjoy a good understanding out on the pitch."
The former Valencia man never managed to produce his best form in the Premier League and, although his attitude endeared him to the Tottenham fans, his performances on the pitch meant that he fell quickly down the pecking order.
Soldado scored 16 times in 76 appearances for the Lilywhites during his two seasons at the club, and he failed to live up to expectations.
Since Soldado left Tottenham, Mauricio Pochettino has brought in Clinton Njie and Heung-Min Son to try and increase his attacking options.
