When the 2017/18 Premier League fixtures come out at 9am BST on Wednesday 14 June the eyes of fans and players will be drawn to their first opponents.
Until last season, most teams would have dreaded to open against the defending Premier League champions since it seemed a guarantee that they could not win.
For the first 24 seasons of the Premier League no reigning champions had opened their defence with defeat. Indeed, out of a possible 72 points over that time, only eight had ever been dropped.
So Chelsea will be looking to resume normal service for defending champions on the opening weekend.
But the Blues' record on opening weekends as champions is not perfect.
Of the four previous seasons they defended their crown, Chelsea won their opening match in the first three but the last time, in 2015/16, Jose Mourinho's team drew 2-2 with Swansea City.
