More excellent patient passing and build up from Brighton eventually sees Alzate unmarked and in space 25 yards out in centre field.
He lines up the shot right footed and fires low into the bottom right corner. Gazzaniga gets down and across quickly and palms away.
Tottenham have holes where they don't want them in their defensive third and Brighton are finding them.
It has been a good start to this game and despite Spurs having two good early chances it has been an even game so far.
Brighton have started well and kept possession well, stretching Spurs in defence.
Sessegnon makes a great run down the left and a long ball from the back from Toby Alderweireld finds him. He's in one-on-one with the keeper, draws him, but then hits the left upright.
His blushes are spared as the flag goes up and he was offside. He's had two chances early on and looks dangerous
Spurs go straight down the other end from the goal kick and Kane gets space on the right edge of the box and delivers a superb cross across the six yard box to the back post to the on rushing Sessegnon, he slides in at the back post but mis-judges the flight of the ball and misses it. Should have scored
Alzate does well to hold onto the ball and twist away into space from Sissoko on the edge of the box and he fires low but wide.

Tottenham's defeat to Chelsea last time out ended a run six Premier League home games without defeat (W4 D2) - they haven't lost consecutive home games in the competition since January.
Brighton have won one of their last seven, with that coming back on December 5 at Arsenal. The ref that day was Graham Scott and he is against the man in the middle today
Brighton have never recorded a league double over Tottenham, but having hammered Spurs 3-0 earlier in the season they have the perfect chance to deliver their fans an extra Christmas present
The Sporting Life's best bet for the early kick off is....
Historically the Boxing Day lunch time kick-off fails to deliver much festive cheer, the players look like they've eaten too much Christmas pudding and the atmosphere is generally flatter than usual due to a hungover/tired crowds.So we don't expect much entertainment or goals in this one.
As impressive as the Seagulls have been under Graham Potter, they have the league's fifth-worst away record having won just twice on the road all season.
After losing to Chelsea, Spurs will be keen to bounce back to keep their top-four hopes alive. Backing the hosts to have a low-scoring victory, especially with a major goal scorer and creator in Heung-min Son suspended, is worth considering at a best price of 8/5.
Spurs' record on Boxing Day is exceptional, having not lost in the last 13 games played on December 26. They've won 10 of those!
It gets even better when at home, having last tasted Boxing Day defeat on home soil back in 1991 against Nottingham Forest (1-2).
Brighton, meanwhile are struggling, having won just five points from their last 21 available in the Premier League.
Graham Potter has reacted to Brighton's loss to Sheffield United by making five changes - Shane Duffy, Ezequiel Schelotto, Bernardo, Aaron Connolly and Steven Alzate step in with Lewis Dunk, Martin Montoya, Leandro Trossard, Dale Stephens and Neal Maupay making way.
Brighton: Ryan, Webster, Duffy, Burn, Schelotto, Bernardo, Connolly, Stephen, Mooy, Gross, Alzate.
Substitutes: Button, Maupay, Bissouma, Trossard, Murray, Montoya, Propper.
Jose Mourinho makes two changes, with Ryan Sessegnon making his first Premier League start for Spurs, and Harry Winks also coming in. Eric Dier drops to the bench while Son Heung-min is suspended.
Tottenham: Gazzaniga, Vertonghen, Sanchez, Alderweireld, Aurier, Alli, Winks, Sissoko, Lucas Moura, Sessegnon, H Kane.
Substitutes: Vorm, Lamela, Dier, Lo Celso, Foyth, Eriksen, Tanganga
