Liverpool are continuing to roll with Steven Gerrard as their most defensive midfielder, while it isn't entirely clear how Arsenal will line up for the big match between the two early on Saturday. Jack Wilshere returns to the team, but is it to displace Alex Oxlade-Chamberlain or simply replace Lukas Podolski?
Oxlade-Chamberlain had an excellent game in the center of midfield, but he will probably operate in a different role this week. Expect to see him back on the wing -- unless Arsenal switches to a 4-3-3 formation. Liverpool's team is equally ambiguous, mostly because Brendan Rodgers has used slightly different formations with the same personnel. Look to see if Steven Gerrard plays as a lone holder or splits defensive duties with Jordan Henderson.
Kickoff is at 12:45 p.m. local time, 7:45 p.m. ET. You can catch the game on BBC One in the U.K. and USA Network in the United States.
