The 27-year-old spent the second half of last season on loan at Mourinho's Real Madrid after falling out of favour at Manchester City.
Despite a successful stint in Spain, the Whites did not make their deal for Adebayor permanent and he has since joined Tottenham for the season.
The Togolese striker revealed Mourinho was thwarted in his attempts to sign him during the summer and eventually urged him to join Harry Redknapp's side.
"I had discussion with Mourinho about the move," Adebayor said.
"He told me 'you have to think of your career and if you have a chance to go to Spurs go out there, score goals and enjoy yourself again on the football pitch'.
"He is a good manager and I have always had respect for that man.
"Even when I came to Tottenham when I was sleeping I got a message from him.
"It is always nice to have a message from Jose Mourinho. He is a nice person and wish him the best of luck in Madrid this season.
"Hopefully he will achieve his target, which is to win the Champions League and the league."
When asked whether a permanent move to Spain was ever in the offing, he responded: "I get on very well Mourinho but Madrid is one of the biggest clubs in the world.
"Politically it is always difficult. There is not just one man deciding.
"If it was just Mourinho, for sure I would be in Madrid now.
"I am happy with what I did last season and he can ask [to sign me], but he cannot make the decision.
"We have been in contact throughout all the holidays and he gave me the go ahead to go to Tottenham and I am very happy to be here today."
Mourinho and Redknapp's friendship is well documented and Adebayor believes the pair share similar managerial traits.
"I would say Harry [is similar] to Mourinho because of the way he treats players and gives you confidence," he said.
"When I went to Madrid that is what I got.
"That sensation when Mourinho said: 'Adebayor we know you are creative, we know what you can do on the football pitch' and he said 'go out there and enjoy yourself - I cannot tell go left or go round because you know what to do on the football pitch.'
"I had the same discussion with Harry and he told me the same thing.
"For me as a footballer, that is what I need."
Adebayor was not only philosophical about his time at the Santiago Bernabeu but also the abuse he received from Tottenham fans in the past.
The Lome-born player has been the subject of abusive chants due to his time at north London rivals Arsenal, which came to a head during the Champions League quarter-final earlier this year.
"For me it is forgiven," he said.
"You know, if I didn't forgive anybody trust me I would not be wearing the Tottenham shirt today.
"When I am not happy, I can't just keep it inside and I will just say it.
"For me, signing for the club and what happened in the Champions League quarter-finals is over.
"Tottenham reached that stage and once again it is Adebayor taking them out so it is normal that they are not happy.
"But you know, at the end of the day, it is football.
"The fans are passionate about it and sometimes it is difficult for a player to take, but we just have to.
"We all have mistakes one day and we all have to learn from it.
"I am a footballer, that is my job, and to be honest you feel like you have been a little bit abused.
"But at the end of the day we know how it is, how fans react sometimes and I take it in a positive way.
"When I was at Madrid I said last season that I would come to Tottenham, forgetting about what they have been singing.
"They were upset because I was scoring goals but now I play for them.
"We have to love each other, walk in the same direction and that is what I am here for now."
