The visitors took the lead when Lacazette lashed a stunning strike beyond Lloris from the edge of the area.
Spurs failed to clear their lines and eventually Aurier’s challenge allows the ball to fall to Lacazette, who takes a touch, before lashing a fierce shot past Lloris at the near post from 20 yards.
However, the lead only lasted a matter of minutes after a costly backpass from Kolasinac allowed Son to race in behind and round Martinez before tapping into an empty net.
From there, both teams had chances to gain an advantage, but Davies’ rasping drive from distance couldn’t beat the woodwork and Pepe narrowly missed for Arsenal from 20 yards too.
80th minute, Spurs took the lead. Son whipped in a dangerous delivery to the front post and it was met firmly by Alderweireld, who cushioned his header across goal and into the far corner to give the host all 3 points.
The result means that Tottenham jump past Arsenal in the table and surge up to eighth place in the hunt for European qualification.
Meanwhile, Arsenal drop to ninth (two points behind their opponents).
