After 18 months of speculation, Dele Alli has completed a move to the Premier League with Tottenham Hotspur.
He secured his switch to White Hart Lane on at the very death on transfer deadline day, and will remain with MK Dons on loan until the end of the season.
The fee is understood to be £5 million with add-ons based on performance.
The 18-year-old midfielder has scored 12 times for Dons this season, including a second career hat-trick against Crewe Alexandra.
Alli signed a five-and-a-half-year deal with Spurs, saying: “It’s a massive club and I’m really happy to be here.
“I’m really looking forward to meeting all the lads and getting to work with the manager. It’s a dream come true.
“I’d love to play for Spurs and at White Hart Lane. It won’t be easy and I’ll have to fight for my place in the team but I’ll work hard to do that.
“It was a difficult decision to leave a club that I’ve been with since I was a boy because I’ve loved every minute of my time here. I’m really pleased that I’ve been given the opportunity to come back and finish this season – hopefully I can help us be successful.
“Nothing would make me happier than to help a club that’s given me so much reach the next level, which is where we belong. I owe so much to the manager, the Chairman, the staff and players, as well as the fans, who have all been terrific with me from day one.
He added: “I’m so excited about taking the next step in my career with a fantastic club like Tottenham Hotspur. It’s going to be a great challenge for me and it’s one that I’m really relishing. For now, though, my focus is solely on MK Dons and this Saturday’s game.”
Dons boss Karl Robinson added: “We are immensely proud of Dele. He is one of many young and talented players to have progressed through the youth system here, which proves that the chairman’s vision of providing local children with a step into professional football is paying off.
“Over the past three years we have handed first-team debuts to Milton Keynes-based players such as George Williams and Brendan Galloway, who are both now playing at a higher level, as well as help the likes of Liverpool’s Sheyi Ojo earn international recognition - Dele is the latest to follow in that path.”
“We are delighted to have the opportunity to re-sign Dele and keep him with us for the rest of the season. Hopefully both he and us can share some more moments that will last a lifetime, before he moves on.”
