Alli joined Spurs’ Premier League rivals on Transfer Deadline Day.
The 25-year-old brought an end to his seven-year association with the north London club, having joined as a teenager from MK Dons for £5million in 2015.
Alli has now signed a two-and-a-half-year deal at Goodison Park to link up with new Everton boss Frank Lampard.
The deal has been structured to allow Alli to leave on a free transfer, with significant bonus payments included that could reportedly net Spurs up to £40m.
Kane and Alli struck an impressive chemistry in the early years of Mauricio Pochettino’s reign, with the pair netting 57 goals between them in the 2016/2017 campaign in all competitions.
“Good luck on your next chapter @dele_official,” Kane wrote on his official Twitter account.
“We’ve had some great memories together over the past 7 years.
“Thank you for everything you have given me and the club! See you soon.”
