Manchester City beat Chelsea 1-0 courtesy a Bernardo Silva goal at the Ethihad Stadium in an English Premier league game .
Chelsea fell behind in the 46th minute after keeping City at bay in the first half.

Man City were the better of the two sides for almost the entire game and could have added to their tally.
The win means City stretch their lead at the top of the table and Chelsea are currently locked at 5th and could miss out on the Champions League.Â
