The teenage midfielder made his Football League bow at the age of 16 in November 2012 and has taken on a more regular role with the Dons this term.
It has not taken long for his potential to be noted by Premier League suitors, and talk of a January step up is gathering pace.
Liverpool boss Brendan Rodgers was in attendance as the Dons held FA Cup holders Wigan Athletic to a 3-3 draw at the DW Stadium on Saturday, and Alli is said to have been the focus of his attention.
He will have left impressed by what he saw, with Dons manager Karl Robinson of the opinion that he has a 'special' talent on his hands.
Robinson said in the Daily Mirror: "I know Brendan quite well and we speak about different players all the time.
"There may have been another reason why he was at the game, but you've seen Dele and he's special.
"Yes, he did some silly things but he's 17 years of age. He did bits of magic too.
"You don't see many 17 years olds playing in an FA Cup third round tie against a very good Wigan side and not looking out of place.
"I'm very proud of his development."
