That is just about all we have time for tonight, but thanks for joining IBTimes UK for a real festive cracker.
Our next live Premier League coverage comes on New Year's Eve, when Liverpool host Manchester City, Chelsea entertain Stoke and Middlesbrough travel to Old Trafford.
Until then, goodnight.
Southampton, meanwhile, suffer just their second home league defeat of Puel's tenure to date.
The Frenchman may well be unhappy with the sending off of Redmond, but his side were comfortably second best after that Alli equaliser that cancelled out Van Dijk's early header.
They remain eighth in the table and nine points short of the top six. The Saints begin 2017 with a trip to Ronald Koeman's Everton on 2 January before an FA Cup third-round tie against Norwich City and a two-legged EFL Cup semi-final clash with Liverpool.
A real topsy-turvy festive encounter that started quickly and faded badly before a highly entertaining second half.
A 4-1 scoreline slightly flatters Tottenham, but Pochettino will nevertheless be delighted with the both the performance of Alli and the fight shown to secure a third straight league win that ends a run of consecutive away defeats.
Tonight was their first top-flight triumph away from White Hart Lane since 24 September, let's not forget.
Spurs remain fifth, but crucially move to within one point of fourth-place Arsenal. They have also now set a new club record for the most points earned during a single calendar year (71) in the Premier League era.
The only slight negative, aside from Kane's truly woeful penalty, is that both Walker and Vertonghen will now miss the New Year's Day trip to Watford after collecting their fifth yellow cards of the season.
Better to miss that game than the subsequent visit of leaders and rivals Chelsea, however.
Southampton 1-4 Tottenham
Three minutes of added time to be played at St Mary's.
Pochettino makes one final change, sending on the fit again Janssen in place of Kane.
Vertonghen takes exception to a needless late challenge from Long and both players are cautioned.
Two late goals in as many minutes from Tottenham adds some extra gloss to the scoreline.
Rose comes flying down the left-hand flank before cutting inside and beating Romeu. He then finds Alli, who picks out the same corner as Son with optimal precision.
Southampton have been well beaten, but a 4-1 deficit feels a little harsh.
Goal: Southampton 1-4 Tottenham (Dele Alli)
Son wraps up Tottenham's first away league win since 24 September.
After Eriksen's sweeping ball is inadvertently deflected into his path by the head of Romeu, the substitute maintains his composure and coolly slots past Forster.
No coming back for Southampton now.
Goal: Southampton 1-3 Tottenham (Heung-Min Son)
Pochettino's second change sees Winks replace Dembele.
Fonte runs the risk of punishment with something of a wild lunge at Rose. Any real contact there and Southampton could easily have been reduced to nine men.
Speaking of brainless risks, Lloris races out to meet a hopeful long Southampton pass. His weak header falls straight to Hojbjerg, who totally fails to achieve the necessary lift on his shot with the goalkeeper still miles off his line.
Spurs continue to search for a third goal that would put this game beyond Southampton's reach. Van Dijk stands tall to block an attempt from Eriksen.
Tottenham are producing some impressive build-up play now as a latest incisive move ends with Alli firing harmlessly into the side netting.
Pochettino turns to his bench for the first time, withdrawing Sissoko in favour of Heung-Min Son.
Southampton go for broke with a triple substitution after Eriksen crashes the ball off the crossbar.
Pierre-Emile Hojbjerg, Dusan Tadic and Shane Long are thrown on in place of Davis, Sofiane Boufal and Rodriguez.
20 minutes remaining.
Wanyama fools both Davis and Romeu with some more nifty footwork before unleashing a powerful left-footed drive that is palmed over by Forster.
Bertrand then makes an important block to thwart Walker.
A real edge to this game now as Rose enters the book for a crude barge on Cedric Soares near the touchline.
Oh dear. Shades of Roberto Baggio at the 1994 World Cup as Kane sends his penalty over the crossbar and into orbit.
It looked like the ball skipped up off his standing foot before being piledrived into the stratosphere.
A lifeline for 10-man Southampton. Kane immediately looks back at a divot in disgust.
Dramatic scenes at St Mary's as Tottenham break quickly and Sissoko lays the ball nicely into the path of Alli, who fires wide before being awarded a penalty by Mike Dean for an apparent shirt pull from Redmond that initially occurred outside the area.
After a lengthy delay, the Southampton winger is shown a straight red card.
Red card (Nathan Redmond)
Southampton look to test Lloris with their own header before Walker picks up his fifth yellow card of the season for bringing down Bertrand. He will now be suspended for the trip to Watford on New Year's Day.
Tottenham lead for the first time tonight thanks to yet another headed effort.
Fonte is forced to hack the ball behind after Bertrand struggles to deal with a dangerous pass intended for Kyle Walker and Kane, criminally underused in the first half, escapes the attention of Romeu to power home past Forster.
