Steve McClaren was left tearing his hair out after watching his side beaten 3-0 by Sunderland - with referee Bobby Madley feeling the full brunt of his frustration.
But when the dust settles, what will Newcastle's head coach have learned from his side's sixth straight defeat to the Wearsiders?
Newcastle need to curb their enthusiasm:
Fabricio Coloccini saw red in the 45th minute after barging his way into Steven Fletcher. It was a moment of madness and didn't need to make the challenge. Penalty? Definitely. Red card? Up for debate. But what isn't is Newcastle's poor disciplinary record. Newcastle United have picked up 10 red cards in the Premier League since the start of 2014-15, three more than any other side.
Mitrovic miss proves costly:
Newcastle United dominated the opening 45 minutes, time and time again they pressed forward but thanks to a combination of poor finishing and the gloves of Costel Pantilimon, they couldn't find a way through. What proved a vital miss though was Aleksander Mitrovic's miss in the second half, Pantilimon with a superb save.
Sunderland were leading 1-0, the game was on a knife-edge, Mitrovic should have scored and Newcastle were made to pay.
Newcastle back in the relegation dogfight:
Were they ever out of it? No. But the signs looked bright after the 6-2 thrashing of Norwich City last weekend but fast forward a week and a 3-0 away defeat at their fierce rivals has landed Newcastle right back in trouble. And just to rub a bit of salt in those gaping derby wounds, Sunderland leap-frogged Newcastle with the win thanks to their better goal difference.
Horrible History repeating itself:
Newcastle United's recent record against Sunderland is abysmal. Six straight defeats for the Magpies now, with the Black Cats breaking the record at the Stadium of Light. Another quirky stat is that Sam Allardyce is the fourth consecutive Sunderland manager to lose his first game in charge and then beat Newcastle in the derby in his second.
Uncanny. Maybe the defeat was written in the stars? Either way, McClaren won't be getting much sleep tonight.
And finally...it turns out Newcastle United can't spell:
Newcastle United were embarrassed by Sunderland in the end but they didn't help themselves when they somehow managed to miss-spell the name of one of their defenders.
Poor old Chancel Mbemba's name on the back of his shirt had an extra 'M' in it and the television cameras were quick to pick up on it, causing a social media stir!
It was no surprise to see Mbemba come out for the start of the second half with a brand new shirt on, complete with his proper name.
