Manchester City moved 15 points clear at the top of the English Premier league as it extended its winning run to 18 games at Newcastle on Wednesday.
Raheem Sterling's 31st-minute strike was all the leaders had to show for a dominant display in front of a crowd of 52,311 at St James' Park. The Magpies' ultra-conservative approach frustrated them despite their wealth of possession.
But ultimately the 1-0 win was enough on a night when Rafael Benitez's men slipped to a fifth consecutive home defeat for the first time since 1953.
"I'm happy with a lot of clean sheets," City manager Pep Guardiola said. "Today we have started the second round (half of the season) — 18 games left. We're going to see how many we need to be champion."
It might have been worse for Newcastle had referee Andre Marriner taken a dimmer view of Jacob Murphy's first-half challenge on Ilkay Gundogan. Of the incident, Guardiola said: "Everybody is focusing on diving but the referees have to follow the rules and try to take care of the players, so they feel safe."
Newcastle's game-plan was predictably cautious as all 11 men not only got behind the ball, but within 35 yards of their own goal for much of the first half. They challenged City to break them down, which they almost did when Sergio Aguero stabbed Fernandinho's seventh-minute cross against the post.
An early injury to City skipper Vincent Kompany simply prompted Pep Guardiola to replace his central defender with striker Gabriel Jesus.
For all of City's utter domination of possession, it was hardly able to stretch the hosts decisively, although goalkeeper Rob Elliot had to claw away Aguero's 17th-minute header and then come off his line to block Jesus' effort at point-blank range.
The deadlock was broken when Sterling ran on to Kevin de Bruyne's return pass and scuffed the ball past the keeper with the studs of his left boot.
Newcastle might have been back in it had defender Nicolas Otamendi not cleared Rolando Aaron's chipped effort off the line 10 minutes before the break.
There was no change in the pattern of the game after halftime. City came close but the massed ranks of black and white continued to scrap.
De Bruyne struck a post and defender Jamaal lascelles headed just wide of his own goal with Elliot stranded as City went for the kill.
"It was a question of staying in the game until the end," Benitez said, "and I was really pleased with the team in terms of organization and workrate but disappointed because we could have been better on the ball in the first half. I was pleased with our reaction in the second half."
Struggling Swansea hire Carvalhal
Swansea: Swansea hired Carlos Carvalhal as its fifth manager in barely two years on Thursday with the task of keeping the disjointed team in the Premier league.
The 52-year-old Carvalhal arrives in south Wales having parted company with second-tier northern English club Sheffield Wednesday on Sunday following a seven-game winless run that led to fans calling for his dismissal.
Swansea has taken a gamble on the journeyman Portuguese coach with no previous Premier league coaching experience despite being bottom of the standings and five points from safety with 18 games remaining.
"In this moment, maybe if you ask 100 people who follow football, they will say Swansea are going to get relegated," Carvalhal said. "This is the general idea. Maybe some people will say we need a miracle. But when things are in the hands of men, it's not a miracle you need.
"It's in our hands and we can manage things. We don't need divine help. We need strong commitment to move things forward. I promise we will try very hard to change things around."
Carvalhal has only been given a contract for the second half of the season at Swansea, but there is an option to extend it. Swansea has won one of its last 12 games, with the latest loss a 5-0 collapse at liverpool on Tuesday.
"It will be tough," Carvalhal said, "and we will need the support of everybody."
Especially from restless American owners Stephen Kaplan and Jason levien who fired Paul Clement last week before he completed a year in charge.
"We felt we needed to get the managerial situation resolved as soon as possible and while the timing is not always perfect, we can look forward to the second half of the campaign with renewed optimism," Swansea chairman Huw Jenkins said.
Carvalhal's mission is to keep Swansea from being relegated into a division he couldn't get out of at Sheffield Wednesday. The inability to gain promotion did not deter Swansea, having impressed at Hillsborough by constructing a hard-working team playing free-flowing football and with an attacking mentality.
"Carlos' time at Sheffield Wednesday, which included securing two consecutive playoff places, highlighted that he has great character and personality to lead the squad and the football club, which is vital at such a crucial time," Jenkins said.
It's not the first time hiring Carvalhal has seemed a gamble. He had been out of work for three years when he was handed his first job in England in 2015 by Sheffield Wednesday.
