Bale completed his return to Spurs on Saturday, signing a season-long loan from Real Madrid where he spent the last seven years.
Mourinho tried to bring the Welshman to the Bernabeu 12 months before he eventually arrived and then also wanted to sign him at Manchester United.
“I’ve enjoyed it. I’ve said before I love living there, my family’s settled, my kids are happy and I’ve enjoyed being at the club,” he added.
“Obviously there’s ups and downs at every club wherever you go. Maybe the highs have been incredibly high and the lows maybe have been a bit lower but I’ve enjoyed my time there, I enjoyed playing for Real Madrid and achieving what we achieved, achieving what I achieved.
“But it’s time for the next chapter in my career. I want to continue to win trophies and I want to do it with Tottenham.”
