The Magpies were convincing winners against Birmingham City on Saturday and Benitez has opted to keep faith with the same players at the DW Stadium.
Ayoze Perez returns from illness to take a seat on the bench, in place of Cheick Tiote. Karl Darlow continues in goal and plays behind a defence of Vurnon Anita, skipper Jamaal Lascelles, Ciaran Clark and Paul Dummett.
Isaac Hayden again partners Jonjo Shelvey in midfield with Matt Ritchie and Yoan Gouffran - who scored at the weekend - on the flanks. Mohamed Diame starts against his former club and will play behind 16-goal Dwight Gayle.
Alongside Perez on the bench are Chancel Mbemba, DeAndre Yedlin, Achraf Lazaar, Christian Atsu and Aleksandar Mitrovic, with Matz Sels the potential replacement goalkeeper.
