However, they failed to make the most of it and the Red Devils secured a comfortable win.The Blues enjoyed 67% of possession during the game and had 11 shots on goal as compared to Manchester United's seven.Chelsea's are currently witnessing a rough patch after a promising start to the season and are 6th in the Premier League table, one point behind the 'top-four'.
