In the middle of Chelsea's most chaotic season in decades, a semblance of normalcy has broken out.

The struggling champion's 3-0 win away to Crystal Palace on Sunday was its fourth consecutive game without defeat, a run which began in the wake of Jose Mourinho's firing.

Chelsea had previously failed to win away in the league since August, and Sunday's clean sheet was its second in a row for a team which has already conceded almost as many goals as it did when cruising to last season's title.
