Dembele marked his full debut with a goal in Wednesday night's Carling Cup second-round thrashing of Port Vale and is pushing for another start.
Fellow new signing Rafik Halliche could make his bow in defence, but goalkeeper Mark Schwarzer (back) may miss out again, while Philippe Senderos (Achilles), Andrew Johnson (knee) and Diomansy Kamara (foot) are long-term injury absentees.
Cottagers (from): Schwarzer, Stockdale, Zuberbuhler, Kelly, Konchesky, Pantsil, Baird, Hangeland, Hughes, Halliche, Stoor, Gera, Murphy, Duff, Riise, Etuhu, Dempsey, Milson, Greening, Davies, Dikgacoi, E Johnson, Zamora, Elm, Dembele, Briggs.
