Alli fell out of favour while Mourinho was in charge of the North London side.
However, he is now a regular pick under the new manager, Nuno Espirito Santo.
The 25-year-old has taken up a role as part of a midfield three, under Nuno and has played every minute in the Premier League so far.

Alli has now spoken on the difference between the two coaches.
He told BT Sport: “It’s been about us, what we’re going to do and how we are going to set up rather than worrying about the opposition.
“With Mourinho, there was a lot of meetings analysing the opposition.
“The formation we are playing at the moment allows me to be freer as a box-to-box.
“I like to be the engine of the team, not just scoring goals but getting back and defending too.”
