Arsenal-West Ham United Preview (The Associated Press)

After having their EFL Cup title dreams dashed in midweek, both Arsenal and West Ham United seek to regroup Saturday in a London derby at Olympic Stadium. The Gunners (8-4-1) had their 19-match unbeaten streak in all competitions come to an end with a 2-0 home loss to Southampton - their first defeat since opening with a 4-3 setback to Liverpool on Aug. 14 - while the Hammers' second match in four days at Old Trafford resulted in a 4-1 defeat to Manchester United that extended their overall winless streak to five (0-2-3). Arsenal manager Arsene Wenger overturned nearly his entire starting XI for the EFL Cup match, and their youthful inexperience showed against a Saints side that also made substantial changes since it is juggling Europa League commitments around domestic action.
