Playing at home is a distinct advantage for Chelsea against the Gunners. Yes, they could use it to put pressure on Arsenal's players with their twelfth man. Arsenal who came with the status of a guest club will also definitely be eyeing a victory to maintain its position in the standings. Here Chelsea has a negative trend in their last 3 matches.
In their last 5 meetings, Arsenal have a slim lead with 3 wins and 2 losses, and in their last encounter in the Premier League Arsenal beat Chelsea at Stamford Bridge, it could be a good investment for them to do it again.
The match for Arsenal will be away conditionally. Chelsea are approaching this match after a devastating defeat to the former Potter team, and they also have a significant loss - an injury to Arrizabalaga, who was very good. They can't rise to the top 4 in any way and the match with Arsenal will not be the easiest task for them. Arsenal look very confident right now and continue to lead the league, maybe Chelsea can be the ones to break that.
