Following a 1-1 draw in the first leg in California, the Quakes are distinct underdogs heading to the elevation of Toluca.
The teams played out a 1-1 draw in the first leg at Buck Shaw Stadium last Tuesday. Alan Gordon scored a late header to give the home side hope after Raul Nava's brilliant volley had given Toluca the lead. Nava is the competition's leading scorer with seven goals.
The Quakes face a massive task at the Estadio Nemesio Díez, where Toluca has a 4-0-1 record in Liga MX play this season, in addition to a 2-0-0 record in CCL action. Toluca defeated Queretaro 2-0 at the weekend, staying second place in the league.
San Jose will welcome back Clarence Goodson, who was suspended for the first leg. The Quakes benefited from yet another late comeback in league play Saturday, coming back from 3-1 down to earn a 3-3 draw against Real Salt Lake.
The winner of this tie will face the winner of Árabe Unido (Panama) and Alajuelense (Costa Rica) in the semifinal. The Central American teams are the only sides left not from MLS or Liga MX.
