Manchester City beat Crystal Palace 3-0 to move level with Barclay Premier League, BPL leaders Chelsea, while Radamel Falco earned Manchester United a 1-1 draw at Aston Villa.
City were missing Sergio Aguero, Edin Dzeko and Stevan Jovetic due to injury, but they secured an eighth consecutive win in all competitions thanks to David Silva's second-half brace and a late Yaya Toure strike. Victory left City level on 39 points with Chelsea, who remain top by virtue of a superior goal difference ahead of their trip to Stoke City on Monday.
"It was a very good win, it was a very good performance. I enjoyed the way the team worked the whole week -- to work in a different way without strikers. I did think December is a key month to be in the fight for the title, and if you want to be involved you must be very near the top of the table. I hope we continue playing like this," City manager Manuel Pellegrini said.
United spurned a chance to close on Chelsea after dropping points for the first time in seven matches at Villa, who had Gabriel Agbonlahor sent off in the 65th minute for a foul on former team-mate Ashley Young. The draw ended United's run of six straight wins and left Louis van Gaal's side seven points off the pace in third place, while West Ham United, Southampton and Tottenham all closed on them.
At the Etihad Stadium, City started with James Milner as an auxiliary striker and after growing into the game, the champions went ahead four minutes into the second half. From Fernandinho's pass, Pablo Zabaleta scuttled into the area before cutting the ball back for Silva, who beat Julian Speroni with the aid of a deflection off Scott Dann.
Silva claimed his second goal in the 61st minute, neatly steering home at the near post from Aleksandar Kolarov's left-wing centre. James McArthur thought he had replied for Palace moments later when he headed Yannick Bolasie's cross past Hart, but although Fernandinho appeared to have played him onside, the assistant referee's flag went up. Toure made the game safe for City in the 81st minute, collecting a square pass from Milner and slamming home left-footed at the near post.
