Kane scored eight goals in six matches last month, including back-to-back hat-tricks against Burnley and Southampton, to finish 2017 with a record tally of 39 Premier League goals.
Vicarage Road was even more brightly bedecked in the club's traditional yellow colours than usual as Hornets fans marked the first anniversary of the passing of their celebrated former manager and ex-England boss Graham Taylor.
Son followed that assist with a drive that hit the post flush from 18 yards out. They can cement that with a win at the home of the England senior team, who Allardyce managed for one game but never at Wembley.
This was Son's 40 goal in 117 appearances for Spurs which is outstanding. A striker as clinical as him might be a little bit embarrassed by the goal though.
The only other player to have done that is Jermain Defoe until yesterday. Everton will need similar to get anything here.
Kane worked hard, dropping deep to bring centre-backs Phil Jagielka and Mason Holgate out of position and that created space for Pochettino's players to run into.
Everton will know that anything more than a defeat will be a pleasing result.
"It's great for Tottenham if they can hang onto their players". Although it was off target, it was turned in expertly by Son.
"It has worked for them in the past, but they don't have enough pace on the counter to hurt Tottenham".
The South Korea star brilliantly turned past Jonjoe Kenny and surged down the left before firing in a low cross for Kane to move level with Sheringham with a simple finish, though replays suggested he had strayed offside. Holgate backed off and Son's shot was turned in by Kane.
Spurs went close to breaking the deadlock on 14 minutes as Son Heung-min header sailed just over the crossbar, following a cross from Christian Eriksen.
Yet the England global Alli delivered the brilliant flick and the Danish worldwide finished calmly. A real threat who often misses out on the plaudits that Kane, Eriksen and Alli get.
