On their coat-tails in the Premier League on Saturday, Manchester City stayed top with a late 1-0 win over Crystal Palace while Manchester United downed Liverpool 3-1 and Arsenal beat Stoke City 2-0 to stay.
Champions Chelsea ended the day in 16th place, 11 points behind the leaders, when they crashed to another defeat, beaten 3-1 at Everton where Scotland striker Steven Naismith came off the bench to score a hat-trick.
City have 15 points from five successive wins, followed by United and Arsenal on 10 and Palace on nine.
Liverpool dropped to ninth after 36 million pounds ($55.54 million) teenage signing Anthony Martial secured the points for United with a dazzling late goal on his debut after Christian Benteke had scored with a brilliant overhead kick for the visitors.
Another teenager, Kelechi Iheanacho, clinched the points for Manchester City when he came on in the 89th minute at Selhurst Park and scored the winner a minute later.
