Nigel Adkins appears to have reverted back to a 4-1-4-1 formation, a change from the 4-2-3=1 he'd be using the past few matches. Jack Cork moves back in to the defense with Morgan Schneiderlin the lone deep midifelder.
Arsene Wenger has put out the same lineup that embarrassed Newcastle 7-3 on Saturday with Theo Walcott as the lone striker, supported by Ox, Cazorla and Podolski. Considering the absurd amount of goal this group hung on the Magpies, it really makes perfect sense for Wenger to not get fancy especially with the Gunners facing a Southampton side that has conceed their fair share of goals this season.
Buckle your seat belts, this could get ugly.
Southampton starting lineup (4-1-4-1): Artur Boruc; Jack Cork, José Fonte, Maya Yoshida, Luke Shaw; Morgan Schneiderlin; Jason Puncheon, Steven Davis, Guly do Prado, Gastón Ramírez; Rickie Lambert.
Arsenal starting lineup (4-2-3-1): Wojciech Szczęsny; Bacary Sagna, Thomas Vermaelen, Laurent Koscielny, Kieran Gibbs; Mikel Arteta, Jack Wilshere; Alex Oxlade-Chamberlain, Santi Cazorla, Lukas Podolski; Theo Walcott.
