Tottenham opened the door for north London rivals Arsenal in the race for second place after suffering a 2-1 defeat to Southampton at White Hart Lane on Sunday.
- Tottenham 1 Southampton 2
- Son gives Spurs early lead
- Davis restores parity for Saints
- Davis then fires visitors in front
- Third defeat for Pochettino's side
Mauricio Pochettino's side got off to a flying start when Son Heung-min opened the scoring on 14 minutes, but a brace from Steven Davis handed the Saints victory to keep their slim European hopes alive.
Spurs, meanwhile, are in danger of seeing their season fall flat at the death following a third game without a win in the league, which has given the Gunners a chance of going level with them in the standings when they take on Manchester City later in the day.
The hosts made the better start in bright sunshine and created their first chance after just five minutes when Christian Eriksen forced Fraser Forster into a smart one-handed save with a shot on the stretch from Danny Rose's cross.
Dusan Tadic then threatened for the south-coast club after he was played in by Sadio Mane on the left, but the winger dragged his shot across the face of goal on 11 minutes.
Spurs then broke the deadlock five minutes later in a move started and finished by Son. The South Korean received the ball just inside his own half and surged upfield before slipping the ball to Erik Lamela, who looked to play in Harry Kane.
However, the striker was in an offside position and left the ball, allowing Son to latch onto it on the overlap and he went past Forster and two defenders before steering the ball home from close range.
Kane then went close with a flick from Kyle Walker's cross that flashed over the crossbar and Eriksen fired straight at Forster from just inside the area.
But the Ronald Koeman's men hit back on the half-hour mark as Tadic was released down the right channel and his first-time cross was converted by Davis at the near post.
Kane was presented with another chance on the stroke of half-time when he beat his marker on the left byline and raced towards goal, but his shot was turned behind at the near post.
The visitors started the second half in positive fashion and Tadic sent in another dangerous cross that was headed wide by Shane Long on 54 minutes.
They would take a surprise lead on 72 minutes after a quiet spell, Davis gathering the ball on the left outside the area, played a one-two with Tadic before guiding the ball inside the right post just out of the reach of a diving Hugo Lloris.
The north Londoners went in search of the equaliser and Eric Dier got on the end of Walker's cross on 84 minutes, but steered his header off target.
Nacer Chadli had a final chance to level the scores in stoppage time when Eriksen's free-kick dropped kindly at his feet, but the midfielder's shot was saved by Forster to ensure three points for the visiting team.
