Newcastle may have beat Tottenham but Dan Burn will probably have a sleepless night after putting the ball in his own net during the 2-1 win at St James' Park.
Spurs will come away frustrated after suffering defeat but playing well for large periods of the game.
Alexander Isak secured the victory late on with a simple tap-in as the Magpies weathered a second-half storm from the visitors.
Newcastle had led through Harvey Barnes but Tottenham drew level in comical circumstances,
Nick Pope made a mess of a tame James Maddison effort before Brennan Johnson put the ball across goal.

Burn tried to clear the ball but only managed to boot it into his own net.
Adding to Newcastle's delight, their Italian midfielder Sandro Tonali made his first league appearance since being handed a 10-month ban for a breach of betting rules and received a rapturous reception from the home supporters.
Newcastle now have seven points from their first three games, while Tottenham remain on four.
'Generally we weren't expecting to have too much of the ball,' Isak told Sky Sports. 'We wanted to be dangerous on the counter-attack. It wasn't the most beautiful game from our side but we defended really well and scored two so that's good.
'You always have to be concentrated. It's easy to get frustrated. It was a tough game and tough for me - I wasn't at my sharpest.
'Jacob Murphy had a great assist, very selfless, so it was just being in the right place.'
Tottenham manager Ange Postecoglou will rue the scoreline but not the performance as his side had complete control of the contest for long periods and pinned Newcastle in their own half.
But as they let opportunities them pass by there was always the chance the home side would use their pace up front to break and after a couple of warnings they did just that to grab the points.
Isak struck the woodwork with an early chance before Newcastle took the lead against the run of play after 37 minutes.
A quick throw-in allowed Lloyd Kelly to fire in a low cross from the left which was superbly guided into the far corner by Barnes.
Spurs winger Wilson Odobert should have equalised when he was left unmarked at the back post but he steered his volley over the bar before the visitors did level minutes later.
Newcastle goalkeeper Nick Pope failed to adequately deal with a James Maddison shot from the edge of the box and pushed the ball to Brennan Johnson, whose effort was cleared into his own net by Burn.
Tottenham continued to pepper the Newcastle goal but it was the hosts who found the winner thanks to the vision of Joelinton and composure of Murphy to set up Sweden international Isak.
