The 19-year old was the standout young talent in the Football League last season, and grabbed 16 goals from midfield as part of a Dons team pushing for promotion from League One.
Whether he could step up and make an instant impact at Spurs this season was up for debate, however, and there were even suggestions of sending him out on loan earlier this summer.
Any doubts have been well and truly put to bed now - with the England Under-21 international emerging as one of Tottenham’s brightest sparks so far this campaign - and speaking to the LES, Alli was in confident mood.
“I wouldn’t say I’ve surprised myself,” said the promising midfielder.
“It’s a big jump from League One but I’m confident in my ability and I can’t thank the players enough for how they’ve helped me settle in, and for the way I’m performing. It makes it easier for me to play as I know I can.”
Despite his confidence, even Alli could not have envisioned the season starting quite so spectacularly.
He has already notched his first goal and, after several decent cameos, has started the last two Spurs games.
For a player who was expected to be a bit-part contributor at most, it’s a measure of his progress that it is now hard to envisage who will dislodge him from the first XI.
