The exciting 19-year-old signed for Spurs in February but was immediately loaned back to the MK Dons after the £5m deal was completed.
Alli’s fine form has continued since the move as he looks to help guide his club into the Sky Bet Championship, and further reward came on Sunday when he was named Football League Young Player of the Year.
When asked about his impending move to north London, Alli said: “When you go, you don’t want a manager that’s not going to have any trust in young players.
“I think with him (Pochettino) you can see already that he has a lot of faith in youngsters and I think as a young player you need that, just for confidence in yourself.
“You need a manager that believes in you and shows that he believes in you by playing you.
“For a few years now there have been rumours of me going places. I’ve been speaking to my agent to see what it is all about. Obviously the last year really it has picked up a bit and there has been a lot more speculation about me going other places.
“In this transfer window, towards the end, it was a bit of a rollercoaster, to be fair. When it came that I could come to Tottenham, obviously I had a look and I spoke to my agent.
“We had to think about the manager and all the pros and cons about it. We couldn’t think of anything wrong, really, about it – it is the perfect club for me, hopefully. I am just going to do the best I can.”
Alli hopes to repay MK Dons boss Karl Robinson by helping them to promotion – they sit third with three games remaining, but are only one point behind Preston in second.
“While I am at MK, I am just going to be focused on them, right until the end of the season,” he added. “To get promotion would be the perfect ending to a fairytale, really.
“Obviously, being from MK and playing for MK my whole life, to get us promoted would be a dream come true.”
