All eyes will be on the Tottenham Hotspur Stadium on Sunday, December 22, when Chelsea face London rivals Tottenham for the first time this season.
Games between the two sides are usually spicy encounters, but the latest instalment has just taken on added significance, with former Chelsea boss Jose Mourinho taking charge of Tottenham , following the sacking of Mauricio Pochettino.
Mourinho, who has had two spells as Chelsea boss, has been appointed as the new head coach at Tottenham until 2023, with the announcement of his arrival coming less than 12 hours after Spurs confirmed Pochettino's departure.
Understandably, his return to the Premier League has caused quite a stir, with some Arsenal fans delighting in the fact that he has been appointed by their north London rivals, while others are fearful that he enjoy success with Spurs, as he has done previously at both Chelsea and United.
But for Chelsea fans, the reaction has been somewhat different.
Some Blues supporters have reacted angrily to Mourinho's appointment, with others setting their sights set on the first clash with the Portuguese manager as Tottenham boss.
Chelsea and Spurs are yet to meet in the Premier League this season, with the first clash at Tottenham's new home on Sunday, December 22, before Mourinho is set to return to Stamford Bridge on February 22.
Here's what some Chelsea fans have been saying about Mourinho's appointment at Tottenham.
