The highly-rated midfielder moved to Spurs on a five-and-a-half-year deal from the League One outfit on transfer deadline day.
The 18-year-old will remain on loan at MK Dons for the rest of the season and will then return to Tottenham.
Alli has been making a name for himself over the past two seasons and is having a brilliant 2014-15 campaign on a personal level.
The youngster has scored 12 goals in 27 appearances in League One so far this season and is taking his game to a new level.
Alli is understandably delighted to have been recruited by as big a club as Tottenham, and he has underlined a key reason why the move was made easier.
“I like the way the manager has been working, developing the youth and bring a lot of young players in,” the teenager told Tottenham’s official website. “I wanted to come to a club where the manager puts a lot of trust into young players.
“I’d love to play for Spurs and play at White Hart Lane. It won’t be easy and I’ll have fight for my place in the team but I’ll work hard to do that.”
Tottenham manager Mauricio Pochettino has indeed given chances to young players this season, most notable of whom is Harry Kane.
Under the Argentine boss, England Under-21 international Kane has progressed radically and is now one of the best young players in the Premier League.
Alli is still very young and he will not be expected to break into the first team as soon as he returns from his loan spell at MK Dons.
However, the youngster is certainly a very talented footballer who will get his chances if he continues to develop and works hard.
