Tottenham's relegation fears increased after a 2-1 loss at Fulham consigned them to a fourth consecutive Premier League defeat.
Spurs lost for the second time under interim head coach Igor Tudor, who switched to a back four for this London derby but watched his faltering group go behind after seven minutes.
Wilson opens scoring
Harry Wilson scored for a 10th time this season, but Tottenham were furious a push by Raúl Jiménez on Radu Dragusin was not penalised.
Wilson had scored in the sixth minute of the November meeting and punished Tottenham again when Oscar Bobb's cross found the Wales international, who rifled in on the half-volley.
The visitors were incensed about a slight push on Dragusin by Jiménez, but Craig Pawson in the VAR chair at Stockley Park decided it was not enough to warrant a foul.
Contact by Jiménez was soft but the incident was strikingly similar to the goal ruled out for Spurs forward Randal Kolo Muani against Arsenal last Sunday due to a slight push.
Iwobi doubles advantage
Fulham doubled their advantage in the 34th minute when ex-Arsenal midfielder Alex Iwobi fired in from range to leave the visitors with a huge uphill battle.
After a quick one-two with Wilson, Iwobi produced a fine first-time effort into the bottom corner in the 34th minute to stun Tottenham.
Yves Bissouma and Dragusin squandered chances to reduce the deficit before half-time, but it may have been 3-0 had Calvin Bassey not hooked over in first-half stoppage-time.
Late fightback falls short
Fulham remained on top after the break and they should have scored again when Bobb played in Emile Smith Rowe, who fired wide but could have teed up Jiménez for a tap-in.
Micky van de Ven denied Jiménez soon after before Tudor made a triple substitution in the 58th minute.
Pape Sarr, Mathys Tel and Richarlison were sent on and even though Guglielmo Vicario had to make a crucial stop to thwart Smith Rowe minutes later, Tottenham were given a lifeline with 65 on the clock at Craven Cottage.
Tel raced at the Fulham defence and played in Gray, who stood up a cross at the back post for Richarlison to head home.
Fulham weathered the initial storm after the goal before Spurs desperately pushed for a late leveller.
Sarr fired into the side-netting but when Palhinha had a stoppage-time effort blocked, the full-time whistle followed to leave Tottenham precariously close to the relegation zone.
Spurs' winless run in the Premier League extends to a record-equalling 10th match with the 16th-placed outfit still only four points above the bottom three.
