Spurs moved up to fifth place in the Premier League standings after Son Heung-min’s stoppage-time strike secured a dramatic victory for the visitors at Villa Park.
Fifth spot could now offer a Champions League place following City’s two-year UEFA ban for breaching Financial Fair Play rules, although it is yet to officially be confirmed and the champions are appealing.
Mourinho finished second with Manchester United two years ago, 19 points behind City, and joked about whether his former club could be retrospectively handed the title.
“I didn’t lose one single minute analysing UEFA – they have to analyse,” the Portuguese said, when asked about City’s situation.
“If I go into that, I have to ask if the team which finished second in 2018 are going to be champions, yes or no?
“Joking apart, I just think about doing the best we can. At the end of the season we’ll see where we are. If we are sixth or seventh then it doesn’t matter if fifth goes to the Champions League.
“Wolves, Sheffield United, Manchester United, Arsenal, Everton – everyone looks to the table and says, ‘We can do it’. It’s going to be very hard.
“It’s not about huge decisions or small decisions, it’s about the rules, the law, ‘it is or it isn’t’. UEFA punished them but they have the chance to appeal.
“Until the appeal has finished, Manchester City have the benefit of the doubt. At the end of the process we will see if they are punished or not.”
