The 20-year-old Spurs man has gone from unknown teenage quantity to fully-fledged star in less than 10 months.
Dele Alli was perhaps the unexpected star of the most recent season, bursting onto the scene to rise from hotly-tipped teenage prospect to fully-fledged star of club and country.
The 20-year-old racked up 10 goals and nine assists in his debut Premier League campaign and was instrumental for Tottenham Hotspur as the North London club launched a genuine title bid for the first time in recent memory.
His year was admittedly punctuated by occasional displays of ill-discipline, such as his three-match club ban to end the season after he was found guilty of punching West Bromwich Albion midfielder Claudio Yacob in the stomach.
However, his talent is there for all to see and at such a young age he appears to have already become instrumental for club and country ahead of Euro 2016.
Here, in photos, are 11 key moments from the season which turned the youngster into a star.
8 August - Competitive debut vs Manchester United
Alli made his first appearance for Spurs on the opening day of the season, coming on as a substitute with 13 minutes remaining in a 1-0 defeat at Old Trafford.
22 August - First goal vs Leicester City
Two weeks later, Alli came off the bench again to score his first goal for the club, a close-range header to open the scoring against eventual champions Leicester, although Riyad Mahrez equalised moments later.
9 October - England debut vs Estonia
Having impressed so much early on in his Spurs career, Alli was called up by Roy Hodgson for the Euro 2016 qualifying double-header in October and made his debut against Estonia as a late substitute.

Alli's star continued to rise with a tremendous performance in the 1-1 draw with North London rivals Arsenal at the Emirates Stadium, showing a perfect blend of composure and aggression to dominate the midfield battle.
