Manchester City stretched the gap back to 12 points at the top of the Premier League with a 4-0 victory over Norwich with Raheem Sterling scoring a perfect hat-trick
Norwich were on a run of three games unbeaten but, despite threatening in periods of the first half, were undone by a fine strike from Sterling on 31 minutes after Max Aarons scuffed a clearance
Pep Guardiola's side have won all 18 Premier League games when scoring first this season and took that run to 19 as Phil Foden made the game safe on 48 minutes, scrambling a close-range finish home that was given the all-clear by goal-line technology
Norwich knew their fate by this point and City wrapped up the game when Sterling arrived from close range to head home following Ruben Dias' powerful header across goal
 There was still time for the England international to score his seventh career hat-trick - a perfect one at that - when tapping home with his left foot after his original penalty kick had been saved by Angus Gunn
The City machine are now unbeaten in their last 15 Premier League games, winning 14 of those as they power towards retaining the title
Liverpool have a chance to move back to within nine points of the runaway leaders on Sunday when they face a trip to bottom-of-the-table Burnley
Meanwhile, Norwich, who struck the post in the first half with the game at 0-0 via a Grant Hanley header, remain firmly in relegation trouble in 17th place and have played two more games than Newcastle and Everton, who sit directly above them in the table
It is easy to forget Sterling had only scored one Premier League goal this season at the start of December following a stop-start period that perhaps was a bit of a hangover from his dazzling performances for England at the Euros
 But the Sterling we are seeing now is the fully-fit and fully-firing version
 He was outstanding in the 1-0 win over Chelsea and has maintained that level of form since, ripping Aarons apart down the left flank at Carrow Road
His treble takes his tally to eight goals in his last eight appearances against Norwich and he now has 10 goals in total in the Premier League this season
 He is City's top goalscorer in the competition
 There will be more to come judging on his showing
 He is a man in red-hot form
"He was absolutely outstanding," said  Andy Hinchcliffe
"The longer the game went on, the more his quality shone through
"Sterling said he would consider leaving Manchester City and moving abroad during an interview in October - a period when he was out of the team
 The England international, who joined City from Liverpool for £49m in 2015, has less than two years left on his contract at the Etihad
 Jamie Redknapp cannot see how City can let him go
He said: "Sterling is fundamental to Manchester City
 Where could he go? The lure of Real Madrid and Barcelona aren't what they were
 It feels like the right fit at City
 Only Sergio Aguero and Lionel Messi have scored more goals under Guardiola
 Sterling knows where the goal is
 The important moments in games is where he comes alive
 He is an absolute nightmare to play against
""It's a brilliant first goal
 The second one was there and you realise after the goal how confident he [Sterling] is, how aggressive
 In the last game he made an excellent action against Brentford to win the penalty
 He is a guy that always creates something
"He [Riyad Mahrez] is an exceptional player but I want more
 He's clever, he's a goalscorer
 But sometimes I want more
 Sometimes he's a little bit weak in the duels
 We've known each other a long time and he knows the intentions we say to him is in a positive way
"On the face of it, this looks like a typical City victory where the opposition can take little from it
 However, for 48 minutes, Norwich were in this game
Milot Rashica showcased his talents and how much the club have missed him with an excellent ball-carrying performance that got Norwich up the pitch at key points in the match
 Even the formidable Dias had to take one for the team and pick up a card to halt a driving Rashica run that had started inside his own box
If Hanley's header had been two inches to the left midway through the half, this could have been an uncomfortable evening for Guardiola's side
 Norwich lacked quality in both boxes but commitment and speed in transitions were up to Premier League standard
The three-game unbeaten run may have come to an end but there were yet more positive signs for Dean Smith and his side that a survival bid can be negotiated
Norwich face Liverpool at Anfield next Saturday at 3pm, while Manchester City visit Sporting Lisbon in the Champions League last-16 first leg at 8pm on Tuesday
