The Imortal Tricolor have already guaranteed their place in the knockout stages, but a win here would see them finish top of Group C.
Match preview
Gremio secured a vital 1-0 victory against Huachipato last time out, thanks to an early goal from Diego Costa. Renato Portaluppi's side needed a result to avoid elimination from the Copa Libertadores and they were able to get a win to seal qualification.
Their important win saw them leapfrog their opponents and they now sit on nine points, having played a game less than the teams in first and third place.
The Brazilian side now require a win on Saturday against Estudiantes to claim top spot, as they are just one point behind leaders The Strongest.
The hosts boast a strong record against the visitors, having won three out of five meetings, with one loss and one draw.
Estudiantes were in action in the Argentine Primera Division against Godoy Cruz, salvaging a 1-1 draw at the Estadio Jorge Luis Hirschi on Monday.
After falling behind to a Vicente Poggi goal in the 24th minute, it appeared Eduardo Dominguez's men were set to suffer their third consecutive defeat across all competitions. However, Zaid Romero ensured a share of the spoils with four minutes remaining.
Los Pincharratas are winless in their last three matches and are already eliminated from the Copa Libertadores despite having one more group stage fixture to play.
The Argentine side have four points from five matches in the competition, four points behind third-placed Huachipato. With nothing left to play for, the visitors will simply be looking to avoid a hat-trick of defeats against the hosts and a run of four games without a win in all competitions.
