Everything you need to know ahead of the Premier League clash at Stamford Bridge on Sunday afternoon
Four wins from four see Chelsea go into Sunday's Stamford Bridge clash with Arsenal in buoyant form.
Arsene Wenger's side have just two wins from their first four games but recovered from a 4-0 hammering to Liverpool with a 3-0 victory over Bournemouth.
Chelsea have had a longer rest from the first European group-stage game, too, as Arsenal took on Cologne in the Europa League on Thursday evening.
The Blues' crisis talk is already a distant memory, with new signings having arrived and their form improving since a shock opening day defeat to Burnley at home.
