Tottenham midfielder is excited for tonight's game.
Alli is understandably excited to turn out at the stadium where he began his career.
He sent a message out on Instagram to supporters expressing his feelings ahead of the tie.
Alli left MK Dons as a teenage prospect and is now an established Premier League and England star.
It was his form at MK Dons which saw him become one of England's most wanted talents, and had teams kicking themselves for not beating Tottenham to his signature.
Spurs lost to Watford in the Premier League earlier this season and even with a rotated team will want to put that right, and stay in the hunt for silverware.
