Arsenal bench Alexis Sanchez for Chelsea test
Arsenal are without Chile forward Alexis Sanchez for their trip to Premier League champions Chelsea at Stamford Bridge.
Sanchez is on the bench as Arsenal make one change from last week's 3-0 win over Bournemouth with Alex Iwobi taking over from Mesut Ozil, who has not recovered from a muscle injury.
The Gunners have lost two of their first four matches and the most recent away game prior to their trip to Stamford Bridge was a 4-0 loss at Liverpool, which reignited debate about Arsene Wenger's position as manager.
Arsenal have not won at Chelsea since October 2011 and have won two of 21 games against the established top six since the start of the 2013-14 season, but Chelsea manager Antonio Conte feels the Gunners are a threat.
