The Tottenham Hotspur youngster hasn't forgotten about his former club.
The 19-year-old went to watch his old side, who lost 2-0 to the Tigers, and singled out Josh Murphy for praise.
Indeed, Murphy is currently at MK Dons on loan from Norwich City and Alli was impressed with his performance despite his old club's weekend defeat.
Alli had traveled directly to the game after training with the Tottenham first team on Saturday morning.
Alli clearly hasn't forgotten his roots, then, and the maturity all those who work with the 19-year-old have spoken of was once again on show this weekend.
There were a variety of things the Tottenham midfielder could no doubt have done with his time on Saturday considering Spurs are in action on Monday night this week.
But he chose to watch his old club and MK Dons will likely appreciate the support. Alli's former club currently sit 20th in the Championship, one point above the relegation zone, having been promoted from League One last term.
