Tottenham missed the chance to move into the Premier League's top four after a 1-1 draw at West Ham, while Newcastle were also held 1-1 by Everton on Tuesday.
Spurs have made a habit of recovering from slow starts to win in recent months, but this time they failed to capitalise on scoring after just five minutes.

Tottenham close to within two points of Aston Villa in fourth and extend their lead over sixth-placed Manchester United to nine points.
"Disappointed not to get a better outcome, but a tough game," said Spurs boss Ange Postecoglou.
"There's a lot of games to go still. I will be very surprised if all games aren't tight. Everyone is fighting for something. We have to maintain our levels."
Injury-hit Newcastle's hopes of European football next season were dented by Dominic Calvert-Lewin's late equaliser for Everton from the penalty spot.
Alexander Isak netted for the fifth consecutive game at St James' Park to open the scoring.
The Swede took his tally for the season to 19 as he cut inside Jarrad Branthwaite and slotted into the far corner on 15 minutes.
"Alexander Isak is an outstanding technician," said Newcastle manager Eddie Howe. "He looks like he will score in every game at the moment."
How Sean Dyche longs for a striker of Isak's quality. But Calvert-Lewin ended a near six-month goal drought from the spot after Ashley Young was hauled down inside the box by Paul Dummett.
Everton set a new club record winless run of 13 Premier League games to leave their 70-year stay in the top flight still at risk.

Fulham boss Marco Silva showed his disgust by making a triple substitution after just half an hour.
However, even that did not halt Forest's momentum as Morgan Gibbs-White made it 3-0 in first-half stoppage time.
"It's important but it can not distract us because we have a long way to go," said Forest boss Nuno Espirito Santo.
"We've had good performances before and not been able to sustain them so let's take that into this game and try to sustain the performance."
Fulham pulled one back through Tosin Adarabioyo in the second half but it was too little, too late for the Cottagers.
