4. In-form Blues
After two poor seasons in the Premier League, Chelsea have started this campaign particularly well and currently sit fourth in the table. The Blues have won five, drawn three and lost two in the league so far under new manager Enzo Maresca.
The two losses came against tough opposition, in the form of the top two Manchester City and Liverpool. Chelsea have certainly had a great improvement this season and look to be a tough side to beat at times.
Off the back of an emphatic 8-0 win over FC Noah in the Europa Conference League, Chelsea will no doubt pose a threat to Arsenal and Mikel Arteta must ensure his squad are not on their A game.
