The Gunners are presently top of the table with 29 points, six ahead of the Blues. Ahead of the London derby, Arteta has provided some positive news on the injury front.
The Gunners boss revealed that Kai Havertz and Viktor Gyokeres are very close to returns and will be assessed during tomorrow's training session before a final decision is made.
The Spaniard added that Trossard's injury in midweek was not serious and he will undergo a further scan. He seemed hopeful that the Belgian will make the matchday squad.
Arsenal are unbeaten in the last 16 games in all competitions, but they face a stern challenge when they take on the Blues at Stamford Bridge on Sunday.
They have dominated the fixture of late with five wins and two draws, but can't underestimate the Blues, who have proved a tough opposition at home.
