Alli, 19, signed for Tottenham almost a year ago, but stayed on loan at Milton Keynes Dons, helping them win promotion from League One, then linked up with Spurs before the start of this season.
The youngster dubbed as the new Steven Gerrard had been tipped as one for the future, but few could have predicted the incredible impact Alli has made at White Hart Lane so far, with the teenager becoming an instant fan favourite.
Alli has not only racked up five goals and three assists for Tottenham in the Premier League this season, but he also scored a superb goal in his first start for England against France, putting himself in contention for Euro 2016.
The plaudits have been pouring in for Alli this term, and he was rewarded for his performances on Tuesday morning, as Tottenham handed him a new contract just a year into his Spurs career.
The Mirror claim that Alli's new deal will see him double his money, earning £25,000-per-week - and now his manager Mauricio Pochettino has hailed him too.
Pochettino has told The Mirror that Alli is a versatile player who shouldn't be placed in a box, before comparing him to Juventus' world-class superstar Paul Pogba, who is one of the top midfielders in the game.
"Today, football is about being versatile," said Pochettino. "We need to help a player like Dele Alli improve, not put him in a box. He needs to feel free on the pitch and we need to help him improve in different positions because a versatile player, like Pogba, has a big, big value."
"He’s a special player. He is box to box but he has real skill on the ball. When he plays like a number 10 he makes the movement like a striker and when he plays number eight or number six he plays like a holding midfielder," he added.
Do you think Alli can become Tottenham's very own Paul Pogba?
