Manchester United completed their first home and away Premier League double over Manchester City since the Alex Ferguson era with a 2-0 victory at Old Trafford on Sunday.
The win moves United up to fifth and leaves Pep Guardiola’s second-placed City trailing leaders Liverpool by 25 points.
United’s opening goal was straight off the training ground with Bruno Fernandes surprising City’s defence with a sharply-taken chipped free-kick over the top to Anthony Martial whose volley sneaked under the arm of the diving Ederson.
City had a Sergio Aguero effort ruled out for off-side after the break but without the injured Kevin De Bruyne, the champions lacked their trademark midfield dominance.
United substitute Scott McTominay made sure of the points in stoppage time after a dreadful throw-out from Ederson straight to the Scotland midfielder, who superbly drove the ball into the unguarded net from over 25 metres out.
Ole Gunnar Solskjaer’s United are now unbeaten in 10 games in all competitions.
The last time United completed the league double over City was in the 2009/10 season.
Chelsea thump former manager Ancelotti's Everton
Two goals in each half from a rampant Chelsea earned them a 4-0 victory over Carlo Ancelotti's Everton on Sunday, cementing their place in the Premier League's top four.
Mason Mount scored the first in the 14th minute, bursting from midfield and playing a one-two with Pedro before controlling the ball, turning and shooting low into the corner.
Seven minutes later Spain's Pedro, revelling in space, latched on to a fine through ball from former Everton midfielder Ross Barkley and picked his spot to the left of the advancing Jordan Pickford.
The home side doubled their lead in three second-half minutes.
In the 51st the indefatigable Barkley set up Willian to shoot across goal and into the far corner from 20 metres with Pickford stranded.
Then France striker Olivier Giroud poked the ball home from a Willian cross after a corner.
Everton coach Ancelotti, who spent two years at Chelsea, leading the team which included current Chelsea boss Frank Lampard to the league and FA Cup double in 2010, enjoyed a warm greeting from the Stamford Bridge crowd on Sunday.
Yet he cut a forlorn figure on the touchline, his team managing only one shot on target.
They lie in 12th place in the table, 11 points behind fourth-placed Chelsea.
