Nine points separate Saint-Etienne and Paris Saint-Germain in Ligue 1, but that gap could close if Les Verts can upset the table-toppers on home turf.
Saint-Etienne are in good form heading into the league clash due to their unbeaten run in their last five outings, two victories coming at the Stade Geoffroy-Guichard.
In contrast, PSG suffered a blow earlier this month when they failed to break the deadlock in a 1-0 defeat to Reims, but have since got back on track with a 2-1 win over Nancy.
David Beckham is likely to start on the bench for PSG, who will face Barcelona in the Champions League quarter-finals, while Zlatan Ibrahimovic should lead the line.
Meanwhile, Saint-Etienne are likely to slot Loic Perrin and Mathieu Bodmer in midfield for Sunday's meeting.
