Man City's Silva delighted with his two-goal brace
Silva had scored only one goal previously this season and his recent return to form has given City a lift after losing Yaya Toure for the African Nations Cup.
The Spaniard said: "It was great to get two goals and I had the opportunity for a third, for the hat-trick, but I didn't make contact as good as I wanted. But it is the points for the team that really matter.
"It was a good game, the important thing was to get three points and put some pressure on United."
