Mexico and Switzerland clash in Group B on Wednesday with both sides still in with a chance of making it into the quarter-finals.
Mexico currently sit top of Group B with four points, while Switzerland have one point following a draw against Gabon on the opening day of the competition.
Switzerland have claimed an Olympic football medal just once, in 1924, while Mexico have yet to triumph in the competition.
Mexico are expected to hand a start to Giovani dos Santos following his double against Gabon, while they have no injury concerns to contend with.
Meanwhile, Switzerland are expected to remain unchanged from their clash with South Korea, with Diego Benaglio continuing in goal.
Possible lineups:
Mexico: Corona; Jimenez, Mier, Reyes, Salcido; Ponce, Aquino, Reyes, Herrera; Dos Santos, Jimenez
Switzerland: Benaglio; Affolter, Daprela, Klose, Schaer; Abrashi, Buff, Frei, Kasami; Emeghara, Mehmedi
Sports Mole says: 2-0
