Arsenal's travel woes against top six rivals

Arsenal got back to winning ways against Bournemouth - but Sunday brings a new test of their ability to compete away to the Premier League's leading sides.
Arsene Wenger takes his team to champions Chelsea, where they have not won since 2011 - part of a dismal recent away record against all the clubs who finished last season in the top six.
The Gunners have won only two such games out of 21 since the start of the 2013-14 season, with their last victory coming at Manchester City in January 2015 - since when their record shows five draws and eight defeats, including their current five-game losing run.
