Unai Emery has got off to an encouraging start as Arsene Wenger's successor, overseeing a 1-1 draw with Atletico Madrid and a 5-1 victory over PSG in the ICC so far.
The Spanish boss is available at 13/10 (2.30) with dabblebet to maintain that strong form by masterminding another win over his new club's Premier League rivals.
This pair met five times last campaign and shared four draws, and you can get odds of 5/2 (3.50) on them cancelling each other out once again.
Mesut Ozil, Alex Iwobi and Mohamed Elneny all returned for the Gunners against PSG, although new signing Lucas Torreira may have to wait for his debut despite linking up with squad this week.
Cesar Azpilicueta, Willy Caballero, Antonio Rudiger, Victor Moses and Andreas Christensen all made their first pre-season appearances against Inter.
However, Olivier Giroud, N'Golo Kante, Eden Hazard and Thibaut Courtois are all still yet to return from post-World Cup breaks.
Having appointed Emery back in May and signed five new players by early July, Arsenal have acted quickly as they look to make a fresh start in the post-Wenger era.
In contrast, the Blues have spent most of the summer reportedly wrangling over Antonio Conte’s severance package before finally appointing Sarri, and Jorginho remains the only new signing so far.
Considering the stark contrast in his playing philosophy with Conte’s, it is hard to see the former Napoli boss getting the team up to speed in such a short space of time.
With important players like Hazard and Kante still absent, those 13/10 (2.30) odds look like solid value on Chelsea coming up short against their better prepared opponents.
